It looks like BitBucket is delayed again. Pushes aren’t being picked up. Pushed over 20 min ago.
Readers might need to see your YAML config. It is perfectly possible to add filters to stop a workflow from running at all (and it is valid too, e.g. with tag filters or schedule-only builds).
I’m a little late to the party but I think this was posted while BitBucket was having some issues with their webhooks service: https://status.bitbucket.org/incidents/zzydzdqxyjny
It looks like today they are still showing some spikes but for the most part looks to be better.
