Error while migrating users using signin-migration custom policies

[akshay1298]

I am getting below error while logging in with B2C & calling the legacy idP to migrate user with a visual studio subscription tenant (no help with azure app insights):

Using policy sample - https://github.com/azure-ad-b2c/samples/tree/master/policies/signin-migration

Can anyone please help me with this?

You did not configure for extension attributes. Follow this: https://learn.microsoft.com/en-us/azure/active-directory-b2c/user-flow-custom-attributes?pivots=b2c-custom-policy

And next time, use the auto env setup tool: https://aka.ms/iefsetup

I have used the ief setup tool for my env setup, but am still getting the same error
