Hm, what node and typescript versions are you running? Might be related to a change there and something we need to address (feel free to make a github issue if you can do a small reproduction somewhere)

node is 20 typescript , 5.3.3 on doing some searching found that typescript after some 4.2.4 version introduced some change related to this, idk have any idea, but giving as much details i can

Yeah it would have to be far more recent, or some flag you’ve got switched on in tsconfig that we aren’t aware of Those are quite new versions so it’s possible something has changed

that to i know of, tsconfig has been same since my last push but what instead i have done is just made a seperate trpc package outside my api package (which just had enpoint logics) i raised the issue on trpc repository

Please do add the solution to the issue, it will help future people 🙂 Feel free to close if you’re happy it’s resolved. Might be something we could support properly though

tRPC requires at least TypeScript v4.7, so you can also send a PR that'll update all overrides 🙂 this way you, and other people can keep using this config setting It's TRPCError and TRPCClientError only from what I see that need to be updated

hey @kamilogorek , sorry for tagging you, i had a doubt, on adding override on my codebase in trpc/server node_modules, i am not getting error during build (basically fix the issue), but i am getting this red error that, i can't use override keyword because there is no field named cause in Error class as you can see, but , my app is using lib.es5.d.ts but the trpc i cloned was using the lib.es2022.d.ts which did not give this error just wanted to make sure if this has nothing to do,

Casue requires indeed es2022 to be recognized, so you’ll be fine 🙂
