BitBucket Cloud Push not triggering Pipeline with same repository URL

[simone201]

I've created a new Jenkins Pipeline (really simple) with the Jenkinsfile taken from a repository on master branch. I've also declared in the pipeline the following trigger:

properties([
  pipelineTriggers([
    [
      $class: 'BitBucketPPRTrigger',
      triggers: [
        [
          $class: 'BitBucketPPRRepositoryTriggerFilter',
          actionFilter: [
            $class: 'BitBucketPPRRepositoryPushActionFilter',
            triggerAlsoIfNothingChanged: true,
            triggerAlsoIfTagPush: false,
            triggerOnlyIfTagPush: true,
            allowedBranches: "",
            isToApprove: false
          ]
        ]
      ]
    ]
  ])
])

as per plugin documentation. I've tried enabling the webhooks in the same repository as the Jenkinsfile, also ran manually the pipeline a couple of times to let it enable the trigger (checked in its configuration) but on TAG PUSH is not triggering the pipeline at all, neither on any other kind of trigger.

Here's the log of the plugin taken from Jenkins:

Any idea why is not triggering the pipeline as expected?
