Cannot find the phone number which belongs to user

How did you login your app and what error did you get when you sent an MMS message? Could you send SMS message at all?

Yes I can send SMS messages, following the error code.

Error code 400, bad request

"errorCode":"MSG-245"
"message":"Parameter [from] value [[object Object]] is invalid [Cannot find the phone number which belongs to u..."
"parameterName":"from"
"parameterValue":"[object Object]"
}
