Last time (8 months ago), I created Azure AD B2C and used Custom policy with Funcs: Sign In (Web) --> It worked well. But now, when I create again It cannot work. And this is postman message.
Error message is wrong User & Password.
Any one faced the same issue with me?
This error is caused by the absence of this user name in b2c, which is raised if the user is not created in b2c or registered, as shown in the figure, the user comes from an external ad or guest type.
