In case you all haven’t already fixed this, you can resolve the issue by renaming context.js to context.ts (you may need to support typescript imports in your main app)

This doesn’t seem to be the right approach. Prisma should theoretically support both .js and .ts and should be language agnostic. The right approach would be to fix the code to accept both .js and .ts files.

@Benjaminryejones Thank you for the reply.

When I run npm run build the code runs without an error.
This is in line with your comment, because there is a file named “context.ts” in the /src folder.
This then generates a “context.js” file in the /dist folder.

When I then fun npm run start (which runs node dist/server), that is when the error appears.
It does not feel right to rename this file to “context.ts” at this point.

I guess the problem is in the schema.ts file at this piece of code:

typegenAutoConfig: {
    contextType: 'Context.Context',
    sources: [
      {
        source: '@prisma/client',
        alias: 'prisma',
      },
      {
        source: require.resolve('./context'), // <-- problem here, I guess
        alias: 'Context',
      },
    ],
  },

Is there a way to make npm run start (node dist/server) to run without the error?
