I am having a repo on Bitbucket and it contains code for  Drools. I am having different branches and trying to merge a branch into the master branch. But it ends up with the following error

I create a pull request and can not merge it. It gives the following error:
 I am unable to understand the cause for it. As I am having admin permissions for the repo.
Here are the permissions on my side.

Permissions for me in the repo.

Any ideas about what's wrong with it? Thanks a lot. I am not finding any reason behind the error being the admin of the repo
