I'm hitting the following error when using the GA4 connector: Expression.Error: The field 'description' of the record wasn't found. Details: apiName=customChannelGroup:XXXXXX uiName=YYY...
Thanks for the response. I don't think it's an issue with the query - the error is shown when I use the native Power BI connector to GA. It has occured since we added a custom channel grouping in GA.
