Unkown error when trying to delete record on the sys_user_grmember table

[RobDoyle]

I am currently having issues with adding / removing users from one of our groups.

We have a scoped app made for HR and not the HR module. 

We have a flow that triggers when a user becomes inactive. so it looks up the record in the sys_user_grmember table and for each record we want it to delete the record.

This flow works for global and our other Owner Support scoped app groups but not for HR

There is no business rules in place and I have checked all the ACL's and they look fine 

I have also looked at the cross scope privileges and they match the other scoped app so I am really not sure now why it will not delete the record 

If i go directly into the table i can add and remove manually no issues just the flows cannot.

I have attached screenshots of the error log and the error in the flow executions

Here is another KB article that may help. With your use case it may not be possible to do this, but it might be worth looking into. Also another link that may be worth looking into against your flow

So that does work when running a test as myself but the flow triggers when a user becomes inactive and the flow is run my the system which in turn give me the same error
