I have some dataflows that have been working without issue until recently. These data flows connect to on-premise SQL DB's and pull data out and store it in our organisations Data Lake (ADLS gen 2). ...
after logging a support ticket with MS, the issue is now resolved.
our issue was that the Power BI Service applicaiton wass missing the Storage Blob Data Owner role in our ADLS gen 2 containers.
issue now resolved
