I am unable to initiate initPayload on my existing code with Rasa 3.x

Dear Team, I have created a bot using RASA 3.7.1 and it good active. When I open chat frame with my code (not Botfront), I want chatbot show the message “Hello !” but it can’t. On forum have this question but with Rasa 2.x so it isn’t help me. Help me, please! Thank you so much!

My code: 1> In domain.yml file, I register action_greet 2> In stories.yml file: - story: hello path steps: - intent: greet - action: action_greet 3> In scripts.js file: customActionTrigger(); 4> In constants.js file: const action_name = “action_greet”; const rasa_server_url = “http://localhost:5005/webhooks/rest/webhook”; const sender_id = uuidv4(); 5> In actions.py file: class Hello(Action): def name(self): return “action_greet”

        def run(self, dispatcher, tracker, domain):
            return []

6> In chat.js file: function customActionTrigger() { $.ajax({ url: “http://localhost:5055/webhook/”, type: “POST”, contentType: “application/json”, data: JSON.stringify({ next_action: action_name, tracker: { sender_id, }, }), success(botResponse, status) { console.log("Response from Rasa: ", botResponse, "\nStatus: ", status);

                if (Object.hasOwnProperty.call(botResponse, "responses")) {
                $("#userInput").prop("disabled", false);
            error(xhr, textStatus) {
                // if there is no response from rasa server
                console.log("Error from bot end: ", textStatus);
                $("#userInput").prop("disabled", false);

hi @hana - do you know if the error is that the payload isn’t being sent by the frontend, or that it’s sent but there is no response?

A good way to check is to open devtools in your browser, open the ‘network’ tab and opening your chat frame again to see if the POST request gets sent.
