Mobile Configuration in 2.34.3

Hi Majtaba,
I already did as you suggested:
configuration Template: content=${text}&to_number=${recipients}&provider=rapidpro&secret=secret but the SMS is still FAILED. On the SMS gateway I

am receiving this error message:

{
** “message”: {**
** “status”: “error”,**
** “error”: {**
** “name”: “SyntaxError”,**
** “message”: “Unexpected token c in JSON at position 0”,**
** “code”: 422**
** }**
** },**
** “level”: “error”,**
** “label”: “sms-gateway-prod”,**
** “timestamp”: “2021-04-08T04:38:35.986Z”**
}
