SentryError: HTTP Error (413) with Node Express

Hi,
I’m new on Sentry and working on integrating Sentry with a React app that uses Node and Express for SSR.

Using @sentry/node SDK.
When sending a test error from Express end point I’m getting
Sentry Logger [Error]: Error while sending event: SentryError: HTTP Error (413)
The error is as simple as
throw new Error(“Test”);
Exactly the same code works fine with a local on premise instance, but fails to send to the hosted sentry.io project

Does anyone have any pointers about

  • what could be the problem here? it doesn’t seem to be the actual payload size, as the only difference is which Sentry project it’s being sent to
  • any useful tweaks that can be done on Sentry project itself, related to error sizing, limits, whether it’s possible to add custom preferences
  • getting more insight about what precisely is being sent to Sentry (breadcrumbs, context, general message size and concept)

Many thanks in advance!

Are you sure your DSN is correct for sentry.io?
