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 :
