RELATES_TOProblem

it uploads the file successfully, but just dumps the file on the "root" directory in Vercel blob storage — upload an image for example via the Payload admin upload feature. Tension: This makes my blob storage explorer in Vercel look very messy. Outcome: I would therefore very much like a folder for each project.

RELATES_TOProblem

files should be attached to the binary option when defining the Body of your request in Postman. Outcome: Sorted it out.

RELATES_TOProblem

continuously getting the error: TypeError: Failed To Fetch — I'm using the AWS SDK V3 in my Nextjs application to upload files to s3. Tension: I've previously had this working with no issue but when I changed my secret key on my user today. Outcome: Downgrading to @aws-sdk/client-s3@3.317.0 fixed the issue for me.

RELATES_TOProblem

I have a model that has an ImageField. — I want users to be able to upload multiple images for an object of the model. Tension: not only a single image. Outcome: You cannot store several images in one ImageField.

PERTAIN_TOSolution

look at a service like Vercel blob — since it seems like you are using Vercel. Tension: the image is not loading. Outcome: look at a service like Vercel blob since it seems like you are using Vercel.

PERTAIN_TOProblem

In a Next.js app, server actions need to be invoked from a component marked with 'use client' to support shadcn/ui form integration, but the current setup fails because server actions cannot be directly executed in client components.

PERTAIN_TOProblem

Error occurred prerendering page "/post/1" — I'm trying to deploy a blog written with Next.js v15.3.3 with Vercel. Tension: TypeError: Cannot read properties of null (reading 'useState'). Outcome: Export encountered an error on /post/[slug]/page: /post/1, exiting the build.

PERTAIN_TOProblem

it uploads the file successfully, but just dumps the file on the "root" directory in Vercel blob storage — upload an image for example via the Payload admin upload feature. Tension: This makes my blob storage explorer in Vercel look very messy. Outcome: I would therefore very much like a folder for each project.

PERTAIN_TOSolution

You can use the `prefix` field to set a sub-directory. — vercelBlobStorage({ enabled: true, collections: { media: { prefix: 'cms_images', }, }, token: process.env.BLOB_READ_WRITE_TOKEN, }). Tension: As of now, there's no fix for this. Outcome: You can manually handle uploads as shown here.

PERTAIN_TOProblem

the URL cannot be directly used — upload videos from a URL when using @google/generative-ai in Next.js. Outcome: the URL cannot be directly used.

PERTAIN_TOSolution

how about downloading the data from the URL and uploading it to Gemini without creating a file? — When this is reflected in the script. Tension: the URL cannot be directly used.

PERTAIN_TOSolution

Use upload(`content/temp/${file.name}`, file, { handleUploadUrl, clientPayload }) and return the pathname settings from onBeforeGenerateToken()

PERTAIN_TOSolution

Create a POST request to generate a signedUrl on the server — Send that URL to the client and POST the upload form with image to the S3 bucket. Tension: bypassing the server. Outcome: With that url you can POST directly to S3.

PERTAIN_TOProblem

Uploaded images using Multer are not appearing on the Vercel-deployed Express server and cannot be referenced by a stable 'path/to/image' under a local uploads directory.

PERTAIN_TOSolution

Store uploads in the serverless writable temp directory (os.tmpdir()) during the request and then persist the files externally (e.g., upload to object storage like S3) or stream them directly; update the Multer storage destination to use os.tmpdir() and avoid serving from a project-local uploads folder.

PERTAIN_TOProblem

one of my requests to retrieve a photo fails with a 400: BAD_REQUEST error. Code: INVALID_IMAGE_OPTIMIZE_REQUEST — When I execute from my production server. Tension: In staging, the request successfully retrieves this image on the production S3, and production is able to retrieve an image from the staging S3. Outcome: The way I optimized the images was by using an absolute path.

PERTAIN_TOSolution

The way I optimized the images was by using an absolute path. Tension: In this case, the solution depends on the API implementation.

PERTAIN_TOProblem

files should be attached to the binary option when defining the Body of your request in Postman. Outcome: Sorted it out.

PERTAIN_TOSolution

files should be attached to the binary option when defining the Body of your request in Postman. — Postman. Tension: it had nothing to do with Vercel, as I expected. Outcome: All in all, files should be attached to the binary option when defining the Body of your request in Postman.

PERTAIN_TOProblem

EROFS: read-only file system, open '/var/task/public/bb17ad93-017f-4fdf-a2db-713d9a390143.webp' — When i try to upload file to public folder on vercel. Tension: works perfectly fine in my dev environment(local computer) but after deploying to vercel it throws that error. Outcome: you want to persist the file then better to store somewhere, probably in S3.

PERTAIN_TOSolution

Only `/tmp` folder is available — if you want to persist the file then better to store somewhere. Tension: as its a temporary folder. Outcome: better to store somewhere, probably in S3.

PERTAIN_TOProblem

This code works but is not in production. — upload files using an API and then store them inside the public folder of Nuxt. Tension: the file directory will change in production. Outcome: you CANNOT use public folder for serving dynamic images.

PERTAIN_TOSolution

you CANNOT use public folder for serving dynamic images — then create a endpoint that read it. Tension: public folder for serving dynamic images. Outcome: you can try to create another folder in project root then create a endpoint that read it with `fs.readFileSync`.

PERTAIN_TOProblem

we could never get the "uploaded" debug information feature to work — using Yocto to build Rust normally on an embedded device with stripped binaries. Tension: it only ever works when the debug file itself is on the platform. Outcome: So it got solved.

PERTAIN_TOSolution

You basically have to feature flag and it works — [dependencies] sentry = { version = "0.29", features = ["debug-images"] }. Outcome: it works.

PERTAIN_TOProblem

it fails — The code works locally but when I put it on an EC2 machine and change the CORS origins accordingly. Tension: I've checked the URL for 2 hours straight. Outcome: Still the same error below.

PERTAIN_TOSolution

DigitalOcean FARM Linux droplet. Tension: tessaract has significant needs of resources. Outcome: I increased the droplet in 4 Dedicated CPUs and 8GB RAM and it worked fine.

PERTAIN_TOProblem

a `422 (Unprocessable entity)` error is raised, saying that the `file` is missing — I am using a `POST` request for uploading a file to a FastAPI application through Postman. Tension: I selected the `binary` option to upload the file. Outcome: the `file` is missing.

PERTAIN_TOSolution

you should select `Body` -> `form-data` — when using FastAPI/Starlette's `UploadFile`. Tension: the key should then be `files`, for instance. Outcome: upload your file in the `Value` section by clicking on the `Select files` button.

PERTAIN_TORootCause

File ID's are expected only in specific fields of some API requests — Stripe API has a way of uploading files, and its response is file object's `"file_id"`. Tension: I aim to attach (aka associate, reference) an uploaded file by its `"file_id"` to another object (e.g., customer, product, subscription...). Outcome: theoretically you could record a file id on any object's `metadata`.

PERTAIN_TOProblem

Need to attach an uploaded file by its file_id to another Stripe object

PERTAIN_TOSolution

File ID's are expected only in specific fields of some API requests — such as several kinds of dispute evidence. Tension: But as @Lucky2501 mentioned, theoretically you could record a file id on any object's `metadata`. Outcome: theoretically you could record a file id on any object's `metadata`.

PERTAIN_TOProblem

using pre-signed-url, I can't check the file size of each part — multipart upload in my application. Tension: all the options I thought do not appear to be good one. Outcome: I really would not like to get the file in any endpoint of my application.

PERTAIN_TOSolution

JavaScript can access the `size` from the File object — using a UI for the upload. Tension: I really would not like to get the file in any endpoint of my application. Outcome: Use this value to populate the `content-length` header value.

PERTAIN_TOSolution

Use a clean percent-encoded presigned URL and allow access via pre-signed URLs in the S3 bucket policy

PERTAIN_TOProblem

S3 blocking requests (403 Forbidden, no response body) if the filename is constructed from Unicode codepoints — Upload via presigned request - 403 forbidden for Unicode Filename. Tension: filename is constructed from Unicode codepoints. Outcome: Using `x-amz-meta-filename` suggests that the user-provided meta-data is transferred via HTTP request headers.

PERTAIN_TOSolution

$safeName = (new Slugify())->slugify($pathinfo['filename']) . '.' . $pathinfo['extension']; — Backend code that generates the presigned URL. Tension: AWS does not allow Unicode characters in `key`. Outcome: the original filenames will not be preserved anywhere.

PERTAIN_TOProblem

while running an AWS Lambda function. Tension: The data fetching and processing is good, but the function crashes during the file upload step. Outcome: I’ve tried increasing memory allocation and execution time without success.

PERTAIN_TOSolution

Have you checked what your csv file sizes are? — By default lambda gives you 512 MB of storage but it can go upto 10 GB now. Tension: there is a possibility that the temp storage is getting exceeded. Outcome: Lambda Ephemeral Storage Update.

PERTAIN_TOSolution

Be sure to print the bucket name before calling the SDK — before calling the SDK. Tension: to be sure that 'the resource' to which access is denied is as expected. Outcome: the AWS error message is therefore correct.

PERTAIN_TOSolution

You can fix it locally — Settings > Apps > Safari > Advanced > Feature Flags. Tension: Toggle 'Enable experimental network loader' on and off. Outcome: from off to on and off again.

PERTAIN_TOProblem

is not authorized to perform: s3:ListBucket on resource. Tension: I am assuming only s3:GetObject is needed for code. Outcome: What and why there is listing?

PERTAIN_TOProblem

All of the put/upload functions want a set content length. Tension: Building the zip locally is not an option, because the end size of the zip can be tens of GB. Outcome: I essentially need a zip "placeholder" on S3 that I can stream to.

PERTAIN_TOSolution

adding a class that extends `OutputStream` and creates a multi-part upload when the buffer reaches the set limit — AWS minimum is 5MB. Tension: end size of the zip can be tens of GB. Outcome: I set it to 10MB.

PERTAIN_TOProblem

I am trying to put the image to this s3 bucket — I have set all the necessary parameters in environment variables. Tension: $disk->put($fileName, $imageData, 'public');. Outcome: Try verify if you bucket have correct permission.

PERTAIN_TOProblem

The HTTP request cannot be executed: The peer resets the connection. — When I try to upload files to S3 from storage via an application deployed on the stand. Tension: Everything is working locally. All files is uploading without errors. Outcome: com.amazonaws.SdkClientException exception.

PERTAIN_TOSolution

update to AWS SDK for Java V2 ASAP — when using V2 to upload larger files. Tension: The Amazon S3 Transfer Manager API can certainly handle larger files. Outcome: use software.amazon.awssdk.transfer.s3.S3TransferManager API.
