NYeah errorFormatter is passed to the server instance IIRC, but createCaller on the router instance itself.
Maybe something like process.on('error', ...) is what you want?
Maybe something like process.on('error', ...) is what you want?
NYou can also move your errorFormatter to an independent function and consume it in both places
Awe automatically wrap all errors in a TRPCError
Aif you want your own type of error classes for the source of truth you can do a middleware
Ayou need to look at
error.cause for your errorAif (!result.ok && result.error instanceof MyError) { ... }Athis example could help you https://trpc.io/docs/middlewares#logging
You are able to add middleware(s) to a procedure with the t.procedure.use() method. The middleware(s) will wrap the invocation of the procedure and must pass through its return value.
