We are trying to implement this in webassembly blazor(Azure b2c) - which has api, server and client projects.
Could you be able to suggest what are we missing here!?--

The only thing I can suggest is to do as the exception suggests and take a look at what's happening in line 38 of the GroupAuthService which, in my code, is commented out. But the 'authority' Uri should have at least one segment in the path (i.e. https:////...) (Parameter 'authority') error suggests you've got a missing parameter in the Uri path.

Hi @elvogel thanks for your response.
Yes, we are using the same code (it is commented out)
I see that we are getting all null values in IOptions graphConfig

Hi @elvogel We have now gotten little further in this..
We are now trying to figure out what url would it be.. Can we still use "1.6 Graph API version"? "
How to convert the url - "https://graph.windows.net/" + config.Tenant + api + "?" + aadGraphVersion;" to the latest Graph API

has anyone here tried with https://graph.microsoft.com/v1.0
