Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for Vercel, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

Module not found: Can't resolve [module] — works locally but fails on Vercel deployment, often related to path aliases in tsconfig.json is a Vercel failure pattern reported for developers trying to fix vercel deployment module resolution failures where local builds succeed but cloud build cannot resolve paths. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Multiple GitHub issues (#69390, shadcn/ui#3683, community#5084, next.js#16179) confirm recurring Vercel module-not-found errors on deploy while local works. Often linked to tsconfig path alias misconfiguration or Next.js internal compiler differences. Production deployment blocker. Not in covered-errors (covered entry is generic 'Vercel build command failed'; this is specifically module resolution mismatch). Category: Deployment.

Quick fixes

Confirm the exact error signature matches Module not found: Can't resolve [module] — works locally but fails on Vercel deployment, often related to path aliases in tsconfig.json.
Check the Vercel account, local tool state, and provider configuration involved in the failing workflow.
Check the build output, project root, and deployment platform configuration before redeploying.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.
