Sentry trpcMiddleware reports bad request and not found from trpc

[gpichot]

Hello,

I am using trpcMiddleware from node package.

Checking the code, Sentry captures all failing trpc errored procedure calls here

sentry-javascript/packages/node/src/handlers.ts

Line 325 in 3e2c8f4

if (!nextResult.ok) {

This also captures BAD_REQUEST and NOT_FOUND errors from trpc.

Would it be possible to disable this behavior? Or I am missing something and it's best to report this errors too?

Thanks in advance for your reply,
G

Hey @gpichot. If you would like to filter out these errors, you can do so in the beforeSend field of your Sentry.init call!

Hey @AbhiPrasad, thanks for your reply.

Actually I can't. The event I receive in beforeSend does not contain the error information I could filter on.

For instance, I get (for a NOT_FOUND error):

[
  {
    type: 'Error',
    value: 'Resource not found',
    stacktrace: { frames: [Array] },
    mechanism: {
      type: 'chained',
      handled: false,
      source: 'cause',
      exception_id: 1,
      parent_id: 0,
      data: [Object]
    }
  },
  {
    type: 'TRPCError',
    value: 'Resource not found',
    stacktrace: { frames: [Array] },
    mechanism: {
      type: 'generic',
      handled: true,
      is_exception_group: true,
      exception_id: 0
    }
  }
]

take a look at hint.originalException (see docs), are you able to access what you need from that error?

Ok thanks, I missed this second argument :).

I went with:

const WhiteListedErrorCodes = ["UNAUTHORIZED", "NOT_FOUND", "BAD_REQUEST"];

Sentry.init({ 
    // ...
    beforeSend(event, hint) {
    if (
      hint.originalException instanceof TRPCError &&
      WhiteListedErrorCodes.includes(hint.originalException.code)
    ) {
      return null;
    }

    return event;
  },
})
