"No user id found for O365 JWT" error while connecting to Yammer

[Ash_15]

Hi all,

I'm trying to access Yammer API (https://docs.microsoft.com/en-us/rest/api/yammer/userscurrentjson) via my organisation's federation setup.  But I'm getting 'No user id found for O365 JWT ' error

My flow is as follows: 

1. I first call https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/authorize
2. Once user logs in, I make a call to https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/tokento get the access_token from Microsoft.
3. I'm successfully getting the access_token and can see the optional claims that have been added in app registration in the token payload. But even after adding all these claims,  I get the 'No user id found for O365 JWT 'error. Am I missing some claims in my access_token configuration? Or is there something else that's going wrong. Any help or clue will be much appreciated.. Thanks in advance!!
4. Below is a sample token payload (I've posted some dummy values in the fields. My main intention here is to show what all fields are returned in the token) :

I am having the same problem! It looks like the token doesn't have necessary user information! However the article in MS below doesn't mention anything about this!

https://learn.microsoft.com/en-us/rest/api/yammer/oauth-2

and this article leads to this post which is exactly what I have done to access Yammer api:
