Triggers "when" clause with "repo.*" functions always returns false

[hroyg]

Summary

we are trying to implement an argocd notifications trigger, we need the "when" condition to trigger when commit message is equal to string e.g "test",
i think i am following the documentation (https://argocd-notifications.readthedocs.io/en/stable/triggers/#repo) explanation to get that string through repo.GetCommitMetadata function as follow :
when: repo.GetCommitMetadata(app.status.sync.revision).Message == 'test'
tried many variations of it but i always returns false

What happened/what you expected to happen?
expected to get the commit message back from the function and use that info as part of trigger condition
