We have the MergeChecks script in BitBucket and it has been working; however, after upgraded ScriptRunner to version 8.1.0, the script is broken and gave error:
# Script: get the merge from branch value and to branch value, split it by / and get the second value after splitted. compare them and if the values are the same, allow the merge.
# e.g. toBranch = develop/asc and fromBranch = feature/asc/<Jira-issue>
