Customer service reported Case 3717438, which reports an error with message, "cannot setup host: missing value for 'account' field". Config Manager, I think expects a value for host.account as suggested by https://github.com/RedHatInsights/config-manager/blob/518725892e4e560cd1add593393e8a0c0787c1f5/internal/host.go#L95

This error may be blocking the completion of a host creation/update by subsciption-manager.
