Vercel Errors

Vercel deploy errors: build failures, function timeouts (FUNCTION_INVOCATION_TIMEOUT), DNS issues (DEPLOYMENT_NOT_FOUND), edge runtime errors. Most issues trace to env vars, build commands, or function size limits.

Vercel function errors carry codes like `FUNCTION_INVOCATION_TIMEOUT`, `FUNCTION_PAYLOAD_TOO_LARGE`, `EDGE_FUNCTION_INVOCATION_FAILED`. Hobby plan: 10s function timeout, 4.5MB payload. Pro: 60s, 4.5MB. Use streaming responses for long-running operations. Build errors usually point at missing env vars (set them in dashboard, not just locally).
