@Anonymous ,

At what stage are you seeing the error message? Have you made sure to add the metadata tags in the Azure AD ClaimsProvider as described here? This is needed so that B2C can read/write any extension attributes.

<Metadata>  <Item Key="ClientId"></Item>  <Item Key="ApplicationObjectId"></Item> </Metadata>

Please share more details about your custom policy and any trace logs you may have.
