Not able to resume the ML Skills.
Root Cause:
The AI units' licenses are overly consuming, which prevents from resuming the ML skill.
Resolution:
When using Enterprise licenses, once all AI Units are consumed a new ML Skill can not be deployed or start a new pipeline. If an already deployed ML Skill is paused and resumed, it is considered a new skill deployment. To not break any production flow, keep using an already deployed ML Skill (predictions will be counted as overconsumption) or finish a pipeline that is already started.
To resume the suspended skill you need to get additional AI units Licenses.
