The client_info parameter needs to be updated to look like this:
"client_info": { "uid": "c765bd67-ca10-4337-ad54-fa82babad87a-<policy>", "utid": "1350dd1f-7f35-43b7-8d0f-bf80031d668a" }
Where = whatever policy as used for authentication. For example,
"client_info": { "uid": "c765bd67-ca10-4337-ad54-fa82babad87a-B2C_1_signupsignin", "utid": "1350dd1f-7f35-43b7-8d0f-bf80031d668a" }
