node.js - Determine route that causes PayloadTooLargeError

Question

We have a NodeJS app that uses Express. We've seen a few PayloadTooLargeError message start to pop up, but the problem is we don't know whats causing it or how to recreate. The error message also doesn't give us any indication of which route the error is occurring on. Is there a way for the stack trace or error message to detail which route is causing the error? We have quite a few routes with APIs from multiple services, so debugging them all is almost impossible.

Answer 1

Adding a custom middleware that logs the request uri before the route is called will allow you to see which uris are throwing errors.
