Can not save service configuration

Hi Experts,

We are developing CX App for Responsys that connect and send message to our local messaging via Program. When saving message in service configuration page, we can not save data due to error: Bad Request: Name is null as my screenshot below:

Here is payload data when submit in service configuration page:

As the error message, Name is missing. But we don't know where to pass Name in payload or which parameter we are missing. Could you please help us on it?

Thank you so much,

Cuong Tran
