Facing issue whith "Puch Check" hook with BitBucket. Push rejected, even correct JIRA Issue Key

[Kailas]

Hi Team,

Please help I am trying to enforce jire issue key with each push for bitbucket. 
WE just created a test branch and enabled the "Puch Check" hook, but the hook rejecting puch even though the comm it message contains a valid Jira Issue Key.

The Hook Config: 
only 2 checkbox ticked:

At least one commit must contain a valid issue key. If no valid issue reference will be found, the push will be blocked

and

Enable the issue status check

the message I am getting: 

remote: [Syntax check] There should be at least one change-set with a valid issue key <Not even the message I configured>
To {---U_R_L---}
! [remote rejected] repo-test -> repo-test (pre-receive hook declined)
error: failed to push some refs to '{---U_R_L---}'.

Though it seems bit obvious to configure the hook, it is confusing on  what is happening.

Regards,

Kailas
