11.3 U2.3 Start cloudsync task via api fails

[KernelPanic]

Using the API to attempt to start a cloud sync task fails..

The command:
{
"id": "2a6dcb22-ef9f-4861-96bd-46f9798fd2ef",
"msg": "method",
"method": "cloudsync.sync",
"params": [ 1 ]
}
the result:
{'msg': 'result', 'id': '2a6dcb22-ef9f-4861-96bd-46f9798fd2ef', 'result': 2232}

Cloudsync Task:
Status: FAILEDStart Time: Tue Jun 9, 2020, 16:32:01 (Australia/Adelaide)Finished Time: Tue Jun 9, 2020, 16:32:01Error: int() argument must be a string, a bytes-like object or a number, not 'dict'

Any ideas on kicking off a cloud sync via api or cli?
