Used Package Manager

pnpm

Expected Behavior

The code to work correctly

Actual Behavior

I get the following typescript errors:

The inferred type of 'loader' cannot be named without a reference to '.pnpm/@[email protected][email protected]/node_modules/@remix-run/server-runtime/dist/single-fetch'. This is likely not portable. A type annotation is necessary.ts(2742)

The inferred type of 'loader' cannot be named without a reference to '.pnpm/[email protected][email protected]/node_modules/react-router'. This is likely not portable. A type annotation is necessary.ts(2742)

This may be due to pnpm's strict dependencies isolation.

Yes this happens to me as well.

PS: btw @vixalien you said you use npm but i can see .pnpm in the errors

[vixalien]

You're right. That's a mistake from my side
