This question happened when i use new created tenant, the tenant i created about one year ago works well.

I registered a web application, a Sign up and sign in user flow and a profile edit user flow. Then i signed up a account with my own email and logined in. Everything works well. But when i try to use profile edit user flow, the service returned a "server_error:AADB2C: An exception has occurred.".
The link i used is from "Run user flow endpoint" and i removed the "&prompt=login". And when i access this uri again(which doesn't contain "&prompt=login"), browser redirect me to login page, so i need to enter my credentials again.

Expected behavior is when i access profile edit uri again, i can edit my profile directly(just like the old tenant).

We can recurrent the error simply by access twice profile edit flow. when i access the flow second time, it will look like this. And i need to enter my credentials again if i access this uri the third time.

Here is my Profile edit Properties and where i copy my profile edit uri :

    Hi @Zhicheng Liu (CSI Interfusion Inc) • Thank you for sharing required information.

    I tracked the correlation ID in our backend database and found the error to be a known issue due to a recent update in B2C. The product group is already aware of it and an internal MS ticket is opened for this issue. We are working on resolving the issue and might take roughly around 2-3 days to get it resolved and reflect on all tenants.

    Apologies for the inconvenience caused due to this. I will post a comment on this thread as soon as the issue is resolved.

    Regards,
    Aman
