"This is likely not portable" error

Randomly started getting this weird error on my front end, can't find anything online on it. Something wrong with my project config, I'm sure

It appears on my trpc react but also in some other places:

export const api = createTRPCReact<AppRouter>();

Any ideas?

had composite: true in the tsconfig.json, removing that fixed it idk why

I bet @ixahmedxi can tell us

I’ve seen this a lot when the api project has dependencies producing types into the API which aren’t available to the client via node_modules

Composite might end up relating to that behaviour

hmm i remember getting this error as well

but i completely forgot how i solved it

Using monorepo module hoisting or installing the dep in both projects generally fixes it

But there are other magic tsconfig things I’ve seen people do (quite a bit of history in this forum)

hmm I just disabled hoisting to fix some other issue lol

probably what caused it to start happening

You can be more specific in how you disable hoisting, or you can install Prisma into both projects just for the types

Or tsconfig tweaks but that seems fragile and might break other stuff too 😅
