SAP BTP Credential Store Instance - Mandatory parameters for service origin are not specified

Hi,

I am trying to create an instance of an SAP Credential Store service on BTP. I'm using the the "proxy" plan since it's the only available plan.

However, the instance creation fails and gives this error.

It mentions of missing / unspecified mandatory parameters but I am unable to find any documentation as to what parameters should be specified.

Any ideas?

Thanks,

John
