Strange pyspark notebook failure - The Code_Verifier does not match the code_challenge
Hi dbeavon3 ,
AADSTS501481 - Errors starting with AADTS - usually mean something to do with Microsoft Entra ID. Most likely your token which is being used with the user ID, is not working anymore for some reason.
We had a similar issue with D365 Link to Fabric, where an account which was used to create the link had a device removed from its list of devices in Entra ID and out of nowhere we started getting a similar issue which stated the token is not valid. We created a MS ticket and they helped us in solving that.
You can try pausing your capacity and starting it again to see if it helps in resetting the token. If not, I advise you to create a MS ticket.
Thanks govindarajan_d
Thanks, The problem appears to be in the spark UI, and it eventually went away.
There were other strange issues in our capacity that day. I'm guessing there may have been a region-specific outage or degradation. We are in the North Central US region, and I think Microsoft doesn't have as high of a regard for certain regions like this one. I wouldn't expect a public communication about service degradation in the North Central region.
I will keep an eye on it. I have a ticket open with Mindtree, but I'm guessing they won't be able to give me more information than what you just did.
dbeavon3 I hope MS provides a RCA. We have been waiting on our own RCA for past 3 weeks! 👀
From different communications I had with MS, I understood there is a list of lower regions, but exactly what makes up that list, I am yet to find out!
