Unable to insert record in group member table through flow designer

[Toshu]

I have a flow designer developed for AD integration with Servicenow through AD spoke

While trying to add user to group in Servicenow instance after adding the users to the AD group I am getting an error that says "Error occurred while inserting record : null"

I have referred to the KB article available but they do not provide a clear fix as expected

I have already referred to these KBs: https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0827213

And related KBs to this error but unable to find a fix

 Below is the flow with error execution:

Actual flow logic:

Please let me know if you could find the issue?

Since this is still open and receiving replies, here's a link to how I worked around this. The issue has do to with assigning a scoped-app roles: Create Record Action throws "Error occured while inserting record: null"
