💻 Code

This file https://github.com/jgoux/acme/blob/main/apps/api/src/config/trpc.ts is reported with an error that didn't happen before typescript@5.5.0-dev.20240524.

You can try running the type-checking command in the root of the monorepo: pnpm type-check.

🙁 Actual behavior

This error happens:

TS2742: The inferred type of 't' cannot be named without a reference to '../../node_modules/@trpc/server/dist/core/internals/config.js'. This is likely not portable. A type annotation is necessary.

3 export const t = initTRPC.create();

🙂 Expected behavior

The error shouldn't be reported.
