Edge Runtime DB Access Mismatch

edge-runtime-mongodb-access-mismatch

A recurring runtime-environment mismatch where middleware/Edge code attempts MongoDB access (often via Mongoose), but Edge runtime incompatibilities force failures that only surface after enabling middleware. Fix by moving DB work to Node runtime.

MATCHESSolution

Try running — npm config set legacy-peer-deps true. Tension: npm ERR! ERESOLVE unable to resolve dependency tree. Outcome: npm config set legacy-peer-deps true.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

MATCHESSolution

Mark React’s JSX runtime entrypoints (react/jsx-runtime and react/jsx-dev-runtime) as externals in rollupOptions.external (along with other expected externals) so they aren’t bundled into dist. Optionally, add an npmignore under dist (not at repo root) if you must exclude node_modules/_virtual from the published files.

MATCHESSolution

webpack config. Tension: These two solutions can both fix this issue.

MATCHESSolution

Switching to a newer version (Node v18+) via NVM fixed it for me.

MATCHESSolution

./node_modules/.bin/env-subset. Outcome: Now you can run.

MATCHESSolution

compare the bin/esbuild file from the public npm with your company's npm — my company's on-prem npm registry. Tension: the node_modules/esbuild/bin/esbuild file was corrupted. Outcome: see if you can get library re-uploaded.

MATCHESSolution

changed `moduleResolution` from `nodenext` to `bundler` — tsconfig.base.json. Tension: Module not found: Can't resolve '@models/business/Business.model'. Outcome: webpack build went successful.

MATCHESSolution

there is `next-mdx-remote-client` which can be used instead — with the latest version of Next.js. Outcome: A few changes need to be made but it isn't a lot overall.

MATCHESSolution

This is specific to Node installation. — Node installation. Tension: path environment variable for npm binaries is misconfigured. Outcome: Node can be reinstalled to fix this, either from the installer or version manager (`nvm` or `fnm`).

MATCHESSolution

How to fix this issue — Next.js project deployed on Vercel. Tension: SQLite is incompatible with serverless environments. Outcome: Consider cloud databases like Postgres Neon, Turso, or Vercel Postgres.

MATCHESSolution

Upgrade Angular to a version where the CommonEngine bug is fixed, and switch SSR rendering to use AngularNodeAppEngine with server-side routing enabled (instead of CommonEngine). Configure the server routing/app engine accordingly so parameterized routes resolve on direct requests.

MATCHESSolution

In next.config.js. Outcome: allowedOrigins: [ 'localhost:3000', // localhost 'foobar-3000.app.github.dev', // Codespaces ].

MATCHESSolution

Upgrade the `rollup` package to the latest version and redeploy (e.g., `npm upgrade rollup`).

MATCHESSolution

try replacing the following and try again — gem 'eventmachine', '1.2.7', git: 'https://github.com/eventmachine/eventmachine.git', tag: 'v1.2.7'. Tension: some days ago, it works great, but today it started to fail. Outcome: gem 'eventmachine'.

MATCHESSolution

Failed to launch the browser process! — The application works correctly on my local but not on vercel. Tension: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory. Outcome: I have been able to fix this issue by changing the Node.js version to 18.x.

MATCHESSolution

In cluster, click on NETWORK ACCESS > ADD IP ADDRESS > ALLOW ACCESS FROM ANYWHERE — After adding access from anywhere in mongoDB cluster. Tension: this issue was also solved. Outcome: It will add this ip: 0.0.0.0/0 and that's all.

MATCHESSolution

Update the mongodb version and avoid using Mongoose in Next.js Edge Runtime; move the database access to a Node.js runtime

MATCHESSolution

You are going to have to use 11.1.4 — Amplify doesn't support Nextjs 12 yet. Tension: the build is error when starting SSR build. Outcome: use 11.1.4.

MATCHESSolution

There are a few things you can do. The first thing I would try is having a function which evaluates after import — the test setup will do the middleware patch. Tension: your function will return the correct value.

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

Revert to a working Expo/Babel configuration (e.g., roll back the SDK or adjust/revert babel.config.js changes to remove the unsupported '.name' option) and clear the Metro bundler cache/restart so the corrected config is applied.

MATCHESSolution

reverting to Node.js 20.18.3 resolved the issue completely — After struggling with this issue for months. Tension: Node.js 22.13.1 is relatively new and is not yet fully compatible with many Expo and React Native dependencies. Outcome: resolved the issue completely.

MATCHESSolution

db is running — likely prisma is not correctly connecting to db. Tension: schema is up to date: `npx prisma migrate`. Outcome: make sure: db is running schema is up to date: `npx prisma migrate`.

MATCHESSolution

Use environment checks like `typeof window === 'undefined'` to determine server vs client, and start Next.js with Node inspector (`NODE_OPTIONS='--inspect' next dev`) to attach Chrome DevTools to debug server-side code.

MATCHESSolution

if (process.env.NEXT_RUNTIME !== 'nodejs') return; — instrumentation.ts. Outcome: await connectToMongoDB();.

MATCHESSolution

Update @datastax/astra-db-ts to the latest version (e.g., `npm install @datastax/astra-db-ts@latest`) to resolve the client-loading error.

MATCHESSolution

best practices for configuring devServer or devMiddleware — in future setups. Tension: prevent such vulnerabilities. Outcome: without upgrading the entire Vue CLI or webpack stack.

MATCHESSolution

Use a newer runtime base image such as mcr.microsoft.com/dotnet/aspnet:6.0-alpine for the final stage

MATCHESSolution

Possible Fix — Given your setup with Expo and `firebase/auth`. Tension: the refresh token mechanism might not be working as expected on your web build. Outcome: Firebase Auth's persistence is configured.
