9.4.1; Can't merge. Urgent bug.

We have upgraded to 9.4.1 and have a setup where we have

  • 1 approver needed
  • branch must be up to date with master

We have a branch of work. As far as we can tell, there is no reason it should not be merged in.

  • It has been approved
  • It is up to date; we can check the commit hashes in the 2 branches. When we try to update branch our local machine, it tells us it is up to date.

We have a problem that occurs sometimes but not all the time - we have yet to work out any pattern to that.

However, the merge button is not active.

Pasted_image_at_2017_07_26_03_47_PM

Oddly, the JSON being returned specifically says it can be. This is after pressing the rebase button:

Pasted_image_at_2017_07_26_03_45_PM

This is what we see in our console:

"can_be_merged":true

and

"merge_status":"can_be_merged"

Any ideas? Thanks
