any idea why trpc is ignoring the catch expression? it just throws its own error about unique constraint violation

@asheeshh try checking the type of your error. You may need to do an if check against TRPC error first and then throw a new error based on what you're experiencing.

youre asking me to check the error type on the client side?

In the catch, console log out the instanceof for e BEFORE you get into the if statement. @asheeshh

Can you share your current code and the console.log for it?

i just added a console log inside catch to print the error

Put this before your if statement in the catch block. console.log(e instanceof TRPCClientError) If this is true, then that means you will never run the code in your if statement.

nothing inside or outside of the if statements is running the whole catch expression doesnt run when an error is thrown

Without seeing the rest of your code, it's difficult to help you. But try looking at this: https://trpc.io/docs/client/vanilla/infer-types#infer-trpcclienterror-types This explains how to get the type from a TRPCClientError

Pretty sure you need to await the promise inside the try-catch block
