Report #104624

[bug\_fix] Error: Cannot find module './api/route' or its corresponding type declarations. \(ts-loader\)

This often happens when you have a \`route.js\` file in the App Router but you're trying to import it as a default export, or the file path is wrong. In App Router, route handlers must export \`GET\`, \`POST\`, etc. as named exports, not default. Also ensure the file is named \`route.js\` \(or \`route.ts\`\) and is in the correct directory \(e.g., \`app/api/route.js\`\). If you're using TypeScript, check the \`tsconfig.json\` paths and ensure the file exists.

Journey Context:
I was creating an API endpoint in \`app/api/users/route.ts\` and tried to import it in a server component using \`import api from './api/users/route'\`. The build failed because route handlers are not default exports. I also had a typo: I wrote \`./api/users/route\` but the file was in \`app/api/users/route.ts\`, so the relative path was wrong. I corrected the import to \`import \{ GET \} from './api/users/route'\` and it worked. The error message was misleading because it pointed to a missing module, but the real issue was the export style.
