Azure AD B2C Login or Login Policy Error

Question

I try to create a single registration or login policy, but I receive the following error message: An error occurred while creating the policy. “The object was not found when retrieving the extension properties in the tenant“ 73a55309 -.... ”The error was 404 / Request_ResourceNotFound: Resource '7c7ab660 -... does not exist or one of its requested reference property objects is missing.

Despite this error, my policy was created, but I think that it does not work correctly, because I try to register on the default page, and after this action I see a blank page with "Bad request".

EDIT 1: I did all the steps based on https://cgillum.tech/2016/05/27/app-service-auth-and-azure-ad-b2c/

EDIT 2: on the MSDN forum, they suggest uninstalling my b2c-extensions-app, but I don’t know what it is and where I can find it. I checked it on the classic Azure portal -> Active Directory -> My AAD B2C -> Applications that my company owns: there is only my test application.

SOLUTION: They are on the MSDN forum. I created a new AAD B2C and the "b2c-extensions-app" was created automatically. After that, I have no problem creating a policy.
