Upload Workflow Fails Quietly

presigned-upload-metadata-transport-failure

Pre-signed upload workflows break due to mismatched request metadata, buffering/size limits, or transport timeouts—yielding corrupted object keys, unusable prefixes, browser-triggered aborts, or failed parts—so the stakes are missing or wrong artifacts in cloud storage deployments.

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.

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.

requests with the forbidden fields sailed through to the write path. Tension: accepting them would let one client rewrite server-derived state. Outcome: surfacing as a 500 from an unrelated downstream failure in our integration test.

GitHub will NOT allow you to pass workflow outputs into the `secrets:` block of a reusable workflow — chain two reusable GitHub Actions workflows. Tension: `secrets:` for `workflow_call` must come from repository/org/environment secrets, never from dynamic runtime values such as outputs.

The workflow randomly fails at times with errors such as. Tension: iOS 18.0 is not installed. To use with Xcode, first download and install the platform.

"Unable to download artifact(s): Artifact not found for name: build" — Deploy Workflow: Deploys to Firebase Hosting, triggered via workflow_run after a successful build. Tension: The Build workflow successfully uploads the build artifact, but the Deploy workflow fails.

prevent anyone who is not Admin/Owner/Maintainer to be able to create/edit workflow files. Tension: users can just create their own workflow file and access the secrets etc.

No certificate for team 'XXXXX' matching 'Apple Distribution: COMPANY_NAME (XXXXX)' found — Triggered github workflow action, then getting error in Fastfile 'build_app' action. Tension: Select a different signing certificate for CODE_SIGN_IDENTITY, a team that matches your selected certificate, or switch to automatic provisioning. Outcome: Clean Succeeded, ** ARCHIVE FAILED **.

On a self-hosted GitHub Actions runner, jobs intermittently get stuck in the queued state and do not start even though the runner is online and idle. This happens randomly on various workflow steps/jobs.

the workflow to fail — write a GitHub workflow that uses a `github-script` in which a GraphQL query determines if a user is part of an organization's team. Tension: wrong permissions where causing the workflow to fail. Outcome: I was on the right track after all.

GitHub Actions workflows fail randomly when installing setuptools

Error: Invalid contents in the credentials file — firebase app is attempting to initialise. Outcome: I could call firebase api via workflow identity by this code.

the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out — deploying an Angular app to Azure Static Web Apps using GitHub Actions. Tension: the build process completes without errors, but the workflow hangs. Outcome: Azure couldn't do; hence it got hang & the process ran indefinitely.

trying to get an object from my S3 bucket using pre-signed URLs. Tension: I've tried encoding the slashes `%2f` with no change. Outcome: upgrade to the latest SDK, in your case boto3.

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.

the file is remaining in the bucket sometimes with delete markers — when the function runs via the S3 trigger. Tension: If I run the function using the Test button afterwards, it deletes every time. Outcome: I was able to resolve this by using Cloudwatch EventBridge to monitor S3 CreateObject event.

aws s3 sync and aws s3 cp fail with MissingContentLength / stream is not seekable errors

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.

On iOS 18 beta, an app using Amplify Flutter (amplify_storage_s3) fails to upload an image to Amazon S3, returning a StorageAccessDeniedException: S3 access denied when making the API call. The same code works on earlier iOS versions.

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.

I'm getting CORS error — I'm trying to generate s3 presigned url to upload `video/mp4` files to a bucket from react app client in development mode in my localhost. Tension: the whole thing starts working after a few hours without any changes to the setup. Outcome: the presigned url stops giving cors error.

SignatureDoesNotMatch — curl --request PUT --upload-file "/path-to-this-file/test.html" "presigned-url". Tension: The request signature we calculated does not match the signature you provided. Outcome: where did I do incorrectly and how to resolve it?

Uploading to S3 via a presigned PUT URL does not apply the desired object tags even when the server-side PutObjectCommand includes the Tagging parameter.

docs are very sparse — AWS SDK for Swift is still in developer preview. Tension: I want to create a pre-signed URL for an object.

Unit tests cannot deterministically simulate S3 upload failure

while uploading the file from Browser. Tension: Aws error message was misleading, instead of asking us to send the security fields in the correct order it is telling us AccessKEY is not found. Outcome: Just changing the order of the form data in the frontend code worked for me.

aws s3 ls s3://bucketname > out.txt does not efficiently export 10m S3 objects as file URLs

when I try uploading from mobile browsers, the upload just loads forever — I'm building a document uploader using Supabase Storage. Outcome: I've tried using different networks, browsers and devices, but it's still the same problem.

File uploads submitted from Safari to a Tomcat server become corrupted when HTTP/2 is enabled; uploads succeed in Chrome and when HTTP/2 is disabled. The issue affects multiple medium-sized files (a few MB).

Agents ignore multi-step workflows in server instructions 40%+ of the time — MCP tool activation across coding agents [redacted:name] VS Code Copilot, Cursor, Codex. Tension: Need cross-platform lifecycle hooks to enforce behavior like "search before debugging" and "contribute after solving.". Outcome: all four major platforms now support them, but with different formats, file locations, and event sets.
