I've been getting this error all day today. I've tried re-publishing the report/dataset with no results. Activity ID: ee29d266-0191-49fe-b2e2-51869fcb2982 Request ID: 0400bce9-71c6-6a19-aacf-3...
Data source is web OAUTH.
Yes gateway is set and credentials.
I did not remap the data source.
I did remove all scheduled times and was able to apply. Then added them back one by one - no errors this time. Veyr strange, but seems removing the scheduled times solved the issue.
