git push in pipeline fails

[andrew lorien]

Using the example here https://confluence.atlassian.com/bitbucket/push-back-to-your-repository-962352710.html

It fails on the "git push" step

+ git push
remote: Permission denied to update branch develop.        
To http://bitbucket.org/MY_COMPANY/MY_REPO
! [remote rejected] develop -> develop (pre-receive hook declined)
error: failed to push some refs to 'http://bitbucket.org/MY_COMPANY/MY_REPO'

I've tried a few suggestions from the pre-December 2018 "Pushing back to your repository" update, but I don't want to reconfigure the whole repo when the documentation says this should just work now.
git remote -v in the pipeline show that I'm definitely using the HTTPS endpoint, and git pull in the pipeline works.

[Andrew Lorien]

OK, found the solution.

The section "Pushing back using alternative authentication methods" in https://confluence.atlassian.com/bitbucket/push-back-to-your-repository-962352710.html

Working for us now.

Do you have branch restrictions enabled on the target branch?

[andrew lorien]

Yes.

Write access and pull requests are restricted to administrators.  What user/group does the pipeline use?

[Andrew Lorien]

OK, I've allowed "everybody" write permission to the branch, and the example works.

But we have a rule that says we can't allow that.  So I'll go back to working with keys.
