Response from Password Intercept WorkFlow API

I’ve called the Password Intercept Workflow API, identityiq/rest/workflows/Password Intercept/launch. It comes back with response status 200, and response body shows as
{

"status": null,

"requestID": "8106523e7d0a1c66817d0ab46c4b00d7",

"warnings": null,

"errors": null,

"retryWait": 0,

"metaData": null,

"attributes": null,

"success": false,

"retry": false,

"failure": false,

"complete": false

}

Do I need to interpret the response? I see success and complete are all “false”, but the password has been changed in the provisioned servers.
