Approval API for approve request not work - status code 4007

Approval API for approve request not work - status code 4007

Hi,

I define a new service catalog with two stage approval.

1. Stage One => Reporting to

2. Stage Two => CEO

When I want to approve request by API from documentation page, show me this error:

  1. {
        "response_status": {
            "status_code": 4000,
            "messages": [
                {
                    "status_code": 4007,
                    "type": "failed",
                    "message": "Invalid URL"
                }
            ],
            "status": "failed"
        }
    }
I attached my screenshot. What should I do? Or should I do something else?

Thanks for helping
