Integration with Sonarqube analysis fails on branch reports

Body

When analyzing a project in Sonarqube, analysis results may be returned with webhook to PR conversation. However, when analysis is run on a branch (including main/master) the webhook fails and causes a crash (with stack-trace) of the Compute Engine. Is there an API event/path to allow successful integration? Does branch UI have any corresponding location for displaying code analysis?
