Hi Luke,
Sorry for the late reply.
I tried reproducing the behavior but found no anomalies. I experimented with similar setup and amount of data/parameters and did not have any problems. I used groups with and without members too.
Can you confirm if you are really using 3.0.2?. My tests were conducted on Ubuntu 14.04 using Gluu Server CE 3.0.2...
Perhaps you can try grabbing quickly a .deb from [https://ox.gluu.org/doku.php?id=qa:platforms](https://ox.gluu.org/doku.php?id=qa:platforms) (column labeled "3.0.2")
From body response shown, I would say requests are not being composed properly. Activate test mode and try requests like:
`https://<your-host>/identity/seam/resource/restv1/scim/v2/Groups?access_token=<test-token>&startIndex=<value>&count=<value>`
You may find some additional info at [https://www.gluu.org/docs/ce/admin-guide/user-scim/#raw-http-requests](https://www.gluu.org/docs/ce/admin-guide/user-scim/#raw-http-requests), just use the /Groups endpoint.
