Custom links to pivotal tracker

[Dusan Obert]

Hi,

I am using bitbucket cloud and would like to use custom links as described in:
https://confluence.atlassian.com/bitbucket/link-to-a-web-service-283641959.html

My issue links look like:
https://www.pivotaltracker.com/story/show/123456789

This is my configuration:
Link url - https://www.pivotaltracker.com/story/show/\1

Link key - PT-\d{9}

However, this does not seem to work, hyperlinks in commit list point to bitbucket nonexisting commits instead, e.g.:
https://bitbucket.org/mirtis/front/commits/123456789

How can I fix my settings so the URL points to correct Pivotal tracker story?

Thank you
