Node fetch ECONNRESET every few thousand requests: the keep-alive socket the server already closed

▲31 ▼2 @venv.wraith 2026-09-04 4 comments

Problem A Node 20 worker calling one upstream API a few hundred thousand times a day: every few thousand requests, `fetch` dies with It is load-correlated — more traffic, more resets — and retrying by hand always succeeds, which smells like a bug in…

Stripe API version pinning: the account upgrade that changed your webhook payloads and your Charge objects on the same day

▲8 ▼0 @mshah 2026-08-28 0 comments

Problem Nothing in the codebase changed, and suddenly webhooks parse to undefined fields and one API call rejects with a version complaint: Meanwhile invoice emails go out with amounts that no longer match the dashboard, because `invoice.lines`…

Stripe webhook 400 "No signatures found matching the expected signature": clock skew, duplicate deliveries, and the tolerance window nobody set

▲16 ▼0 @iduarte 2026-08-28 2 comments

Problem The raw-payload rule is followed — the endpoint reads `req.text()` and passes it straight to the verifier. Signature verification still fails, intermittently and only on one of three webhook endpoints: Intermittent is the tell: the same…

StripeInvalidRequestError "Invalid positive integer": the 19.99 you sent Stripe that Stripe can never accept

▲9 ▼0 @sberg 2026-08-28 0 comments

Problem The first end-to-end payment test on a new integration, and the API rejects the amount outright: The code reads exactly like the demo, the amount is a perfectly reasonable `19.99`, and nothing in the error mentions where the decimal rule is…

Prisma P2002 "Unique constraint failed on the fields": the race two users win at the same moment, and the retry that actually works

▲17 ▼0 @nreyes 2026-08-27 1 comments

Problem A signup endpoint that intermittently throws `P2002` — almost always when a user double-clicks "Sign up" or a frontend retry fires in parallel with the first request: The application's own pre-check (`findUnique` then `create`) runs on every…

Prisma P2025 "An operation failed because it depends on one or more records that were required but was not found"

▲12 ▼0 @pilic 2026-08-26 0 comments

Problem An update endpoint that 500s whenever the record is missing — which, for a public API, is not an edge case at all: The confusing part: the same route returns 404 correctly for the `findUnique` it runs earlier in the handler. The 500 comes…

Prisma "Unknown argument" after a schema change: the generated client that no rebuild regenerated

▲11 ▼0 @ynasser 2026-08-25 0 comments

Problem You added a field to `schema.prisma`, used it in a query, and validation rejects the query the IDE just autocompleted: TypeScript compiled the code without complaint — `prisma.user.findMany({ where: { emailDomain: ... } })` type-checked and…

Prisma N+1: the `include` you chose over `select`, and the query count that explains a 4-second endpoint

▲14 ▼0 @iduarte 2026-08-24 0 comments

Problem An orders page that takes 4 seconds and, with `log: [{ query: 'stdout' }]`, shows the same items query repeated once per order: Root cause The loop pattern — fetch a list, then query per row — or its sneakier cousin: an `include` on the…

"Cannot find module" on a package that is clearly installed: the exports map that never heard of your deep import

▲9 ▼0 @lfournier 2026-08-21 0 comments

Problem A library upgrade from v2 to v3 — with the same files on disk in `node_modules/@acme/ui/dist/` — breaks every deep import in the app: The file `node_modules/@acme/ui/dist/components/Button.js` exists. TypeScript resolves the import fine.…

Node EMFILE "too many open files": your concurrency limit is a lie someone else's code is breaking

▲10 ▼0 @rvance 2026-08-20 0 comments

Problem A batch job processing 50k files with a "concurrency of 10" promise pool: The pool is 10. `ulimit -n` is 1024. Ten files cannot exhaust 1024 handles — yet the job died within a minute. The math refusing to work is the diagnostic. Root cause…

npm EACCES on global installs: stop sudo-ing npm, fix your prefix

Problem `npm install -g some-cli` fails with: The internet's top answer — `sudo npm install -g` — works once, then poisons your `~/.npm` cache with root-owned files, and every later *user* install throws EACCES too. I have inherited this mess on…

pnpm ERR_PNPM_NO_DST_DIR / broken symlinks after a full disk: the store corruption that every `rm -rf node_modules` fails to fix

▲10 ▼0 @sberg 2026-08-14 0 comments

Problem An install that was interrupted (disk full is the usual suspect), and every attempt to recover fails differently: The classic fix — delete `node_modules` and reinstall — runs, claims success, and the app still crashes at import time with a…
