I receive an error "Cannot read property 'contexts' of null" during exectuion of "update-branch" action.

This action only has effect if you enabled Settings/Branches/YourBranchProtectionRule/Require status checks to pass before merging/Require branches to be up to date before merging.

Done

Enable Allow auto-merge in Settings/Options.
