Repetition Problem With Telegram Bot In Node

[kshontop]

I am developing a Telegram bot that uses the Coinbase API to allow users to make cryptocurrency payments. Everything is working fine until I encountered a problem with the charge creation loop. After creating a charge and pressing the back button to return to the main menu, if I decide to create a new charge, the bot gets stuck in a strange loop and essentially sends the message once again every time I input something. It's like the code never breaks the switch and always waits for input. I am using Node.js with the node-telegram-bot-api library to create the Telegram bot. If anyone has an idea of what's going wrong, I would be happy to hear it. Thanks in advance!

```
if (query.data === "button3") {
      const username = query.from.username;
      const userId = query.from.id;

      bot.sendMessage(
        chatId,
        "ℹ️ Entrez le montant que vous souhaitez ajouter à votre compte :",
      ).then((message) => { 

        bot.on("message", (replyMessage) => {
          const amount = parseFloat(replyMessage.text.replace(",", "."));

          if (isNaN(amount) || amount < 5) {
            bot.sendMessage(
              chatId,
              "❌ Montant invalide. Le montant minimum est de 5€."
            );
            return;
          }
          const data = JSON.stringify({
            "name": `${username}`,
            "metadata": {
              "customer_id": userId
            },
            "local_price": {
              "amount": amount.toFixed(2),
              "currency": "EUR"
            },
            "pricing_type": "fixed_price"
          });
          const config = {
            method: 'post',
            url: 'https://api.commerce.coinbase.com/charges',
            headers: { 
              'Content-Type': 'application/json', 
              'Accept': 'application/json',
              'X-CC-Api-Key': 'b7db06a4-db83-419f-9677-94de4b06bfa3',
            },
            data: data
          };
          axios(config)
            .then((response) => {
              paymentUrl = response.data.data.hosted_url;
              console.log(`Succès de la charge : ${paymentUrl}`);
              bot.editMessageText(
                `Cliquez sur le lien ci-dessous pour payer ${amount.toFixed(2)}€ : \n\n➡️ ${paymentUrl}`,
                {
                  chat_id: chatId,
                  message_id: message.message_id, 
                  reply_markup: {
                    inline_keyboard: [
                      [{text: "🔎 Vérifier la transaction", callback_data:"verify_charges"}],
                      [{ text: "⬅️ Retour", callback_data: "back" }]
                    ],
                  },
                }
              );
            })
            .catch((error) => {
              console.log("Error creating Coinbase charge:", error);
            });
        });
      });
    }

I found the solution a few moments ago.

The problem is caused because .on works as declaration, so if you repeat it, it will be declared multiple times.

In your example, you are declaring .on inside .sendMessage, so it will be declared all times that .sendMessage is executed.

You have to be sure that .on is declared once.

je n'ai pas encore trouvé la solution

J'ai trouvé la solution il y a quelques instants.

Le problème est dû au fait que .on fonctionne comme une déclaration, donc si vous le répétez, il sera déclaré plusieurs fois.

Dans votre exemple, vous déclarez .on dans .sendMessage, il sera donc déclaré à chaque fois que .sendMessage sera exécuté.

Vous devez être sûr que .on est déclaré une fois.

@ChezVolt you test to use "bot.once('... " is similar to bot.on, but is only call one time and the event removed
