gh pr merge panic for enterprise 2.20 #3031
Description
Describe the bug
gh version: 1.6.2
server: enterprise 2.20
I recently upgrade my tool from 1.5.0 to 1.6.x but fount gr pr merge would crash.
Fix in ver.1.6.1 does not help on this issue.
I couldn't find similar issue to this, will close this one if there is any duplicates.
Steps to reproduce the behavior
type gh pr merge in a branch that should have match all criteria and could be merged
$ gh pr merge
panic: runtime error: index out of range [0] with length 0
