Pull request references don't allow me to push after use BFG tool

[Enrique Casale Linde]

Hello,

I'm trying to clean a Big file from the a bit bucket repository (> 2 GB) but the references for pull request don't let me. I make sure there were no PR in the repository.

This are the steps I follow

Step 1

Clone the repository using the --mirror tag to ensure all referenes are copied and what I will have in my local repository is a exact copy of the online repo.

git clone --mirror git://example.com/some-big-repo.git

Step 2

Clean all commit, branches and tags from references to files bigger than 2 GB

java -jar bfg.jar --strip-blobs-bigger-than 2048M OUR_REPOSITORY.git

Step 3

Delete all the unwanted data

git reflog expire --expire=now --all && git gc --prune=now --aggressive

Step 4

Update the changes to the online repository

git config -e
# Change configuration to ignore PR refs
[core]
repositoryformatversion = 0
filemode = false
bare = true
symlinks = false
ignorecase = true
[remote "origin"]
url = ssh://git@bitbucket.XXX.XXXX.ch:1111/XXX/XXXX-XXXX.git
fetch = +refs/heads/*:refs/heads/*
fetch = +refs/tags/*:refs/tags/*
mirror = true

git remote update

git push --force

After the step 4 I received this message

error: failed to push some refs to 'ssh://bitbucket.XXX.XXXX.ch:1111/XXXX/XXXX-XXXX.git'

I have take a look at https://community.atlassian.com/t5/Bitbucket-questions/Bitbucket-reserved-refs-when-cleaning-up-with-BFG-tool/qaq-p/702969 but could not make it work. 

I'm not sure what else I can do besides create a new repository. 

Thank you in advance,

Enrique
