When configuring Jenkins Bitbucket plugin to build "Both the current pull request revision and the pull request merged with the current target branch revision", the -head build starts successfully, but the -merge build fails when fetching the source from git. 

I've attached both logs (head and merge), and simply redacted some sensitive information from them, like team name, repo name and branch name, and have surrounded it with <>.

We're using Bitbucket Cloud.
