Sentry response status code: 415 on error status update

Summary

For some projects , e.g. ops-section-demo on issue resolve/ignore BE returns 400 error with response {message: "Sentry response status code: 415"}. In Sentry UI user whose API key I use to connect to Sentry does have enough privileges to change error status.

Steps to reproduce

Setup Sentry Error tracking in GitLab using API key of the user that has enough privileges to ignore/resolve errors in Sentry UI. Try to resolve/ignore any error via GitLab UI - get error response

What is the current bug behavior?

Sentry error status is not updated, 400 error

What is the expected correct behavior?

Sentry error status is successfully updated
