Jenkins build issue for with Bitbucket webhook trigger for PR

Hi Team,

I’m using git plugin for the source code and created the multi branch pipeline and using the gt for branch source and Scan Multibranch Pipeline Triggers selected the Bitbucket webhook trigger and Trigger on All pushes & Pull request opened or source branch updated. In bitbucket created the webhook with /bitbucket-hook/.

I’m facing issue with PR’s when we open the PR automated build is not getting triggered even though selected in events in bitbcuket and in bitbucket payload is showing sent successfully.

Can someone please help me issue with this?

Regards,
Venkateswar
