HERE:

if (e.decoded) {
   // Truncated
   console.warn(e);
    f_ret = e.decoded; // Decoded message with missing required fields
}
 else{
   **console.log(e);**                        
}

so the code in is permanent loop here :

if (f_ret) {
   return callback(null, f_ret);
 } else {
    **console.log('**************** NEW api_req ****************');
   api_req(api_endpoint, access_token, req, callback);**
}
