SCIM Group Push Error while updating user group membership for group null: Found an empty scim group string

Hi,

I am receiving the below error when attempting to push a SCIM group to my custom SCIM application. I have the same users assigned to the app using another group and have the integration configured to push groups. However, I do not see any requests come in from okta to my app.

There are other threads that are similar but not quite the same.
