Jenkins CI Integration produces error messages with the merge request feature.

Summary

We use the Integration Feature with Jenkins. Since the update from Version 9 to 10.0.3-ee we get an error message then a merge request calls jenkins.

Steps to reproduce

Integrate a Jenkins via Webhook (Jenkins CI, not the deprecated one), use the test button on the webhook and click Merge Requests events.

Current Jenkins Version: 2.73.1

What is the current bug behavior?

Doing a Test for Merge Requests Events returns this error:

If we view the Request Details to the Request, and click Resend Request, we get a HTTP:200 and everything works fine.

What is the expected correct behavior?

A working Jenkins Hook.
