When I originally saw the error message last Tuesday morning, I couldn't find that error literally anywhere on the internet. I searched for the specific phrase "tmdatasourceregistry.cpp" and didn't find anything, so I originally thought our error was internal. After troubleshooting all day Tuesday, I searched again on Wednesday and noticed that others were having the error. That's when I figured that it was a more widespread issue.
We have an internal product team in our company that manages the Power BI platform. After we figured that the issue was external to us (on Weds), we followed up with our product team and they submitted a critical case with Microsoft. Microsoft then reached out to us within 30 minutes or so and we spent a number of hours taking them through the error, trying different things, and submitting our logs/error messages for them to troubleshoot. We got a close out email yesterday for our critical case ticket mentioning that the fix was deployed.
I have had no more issues refreshing the datasets since yesterday morning. We have set the datasets back on auto refresh with no issues.
