How to fix input error on nodejs?

Question

PHP

connected a php script to a bot on nodejs and after the request it should give a link, but it only outputs for the previous message

var runner = require("child_process");
var phpScriptPath = "file.php";
var argsString = "value,value2,value";
runner.exec("php " + phpScriptPath + " " +argsString, function(err, phpResponse, stderr) {
 if(err) console.log(err); /* log error */
 const chatId = msg.chat.id;
bot.sendMessage(chatId, phpResponse );
});

in php just echo = $source;

Answer 1

the script is correct, the error was in the logic
