Azure B2C Custom policies login error

Question

I created custom policies on Azure B2C following this guide.

I used my B2C_1A_signup_signin custom policy for sign up without problems. When I tried to sign in with the created user, the sign in form throws the error: Invalid username or password.

I linked the policy to Application Insights and I found this error: Exception of type 'Web.TPEngine.Providers.BadArgumentRetryNeededException' was thrown.

The same happens when I try to use a custom ProfileEdit policy.

When I use my custom PasswordReset policy it works well.

I couldn't find information about the Web.TPEngine.Providers.BadArgumentRetryNeededException error. What does it mean?

Double check the client id and resource id you are using to log users in, AD will always show connection issues as invalid username/.password for security reasons
