SAXParseException on volume delete

[singlecheeze]

RestError = SAXParseException(not well-formed (invalid token)

I've looked everywhere including:
/var/log/qs/qs_audit.log
journalctl -u qs-jsonrpcd.service -f

{'storageVolumeList': ['API.LUN.000', 'API.LUN.001'], 'searchParams': '', 'deleteOptions': '0', 'flags': '0'}

The error is too ambiguous. I can auth just fine so I know it isn't referring to security token.

curl -u admin:password -k "https://172.16.1.119:8153/qstorapi/storageVolumeDelete?storageVolumeList=API.LUN.000&storageVolumeList=API.LUN.001&searchParams=&deleteOptions=0&flags=0"

setting force flag for a LUN that has an active session does not work either:
curl -u admin:password -k "https://172.16.1.119:8153/qstorapi/storageVolumeDelete?storageVolumeList=API.LUN.000&storageVolumeList=API&flags=2"

as a work around for now, I am doing each deletion manually with storage_volume_delete_ex but it would be nice to use a batch job like LUN creation and updating ACLs/Host masking
