Hi @CRMPowerapps ,
Could you share a screenshot of your current Flow configuration? From the error message, the parameter you set in the Item ID is empty, so I recommend you fill in the identifier.
When choosing a connector, please try to choose Common Data Service instead of Common Data Service (current environment).
When choosing an environment, please choose the same environment instead of current.
Please consider creating a new Flow and testing whether similar errors still exist.
Best Regards,
