Respond to Webhook node does not wait for chat response, added Wait node

Questions
1

My workflow asks users questions to determine their interest in one of 3 areas of an app. The AI Agent is instructed to ask a few questions until it knows exactly what their interested in then route them to proper sub-workflow. Here is the hangup:
If the initial response by the user is not clear enough for the AI Agent to determine what the user is interested in, then the AI Agent will generate a question to ask for clarity. When I test by answering the initial question with an irrelevant question such as “Hi there” the AI Agent generates a question for the user to clarify what their current interest is. The question is then sent to the Respond to Webhook for output to the HTML/Javascript doc to illicit the chat response from the user. The question successfully displays in the chat. Here is where the problem occurs in both of 2 scenarios -

  1. I have tested this with just the Respond to Webhook (without the Wait node) an the workflow does not wait for a response, it will continue on its own, resulting in a false route through the Switch node.

  2. Due to scenario 1, I added a Wait node after the Respond to Webhook node. That seemed to stop the workflow from automatically cycling through again without waiting for the user response in chat. This presented a another problem; Now the workflow waits, but the user response triggers built in error in the HTML/Javascript doc.

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

In case it is needed, here is the HTML/Javascript doc code:

<body>
   <div class="container">
       <h1>MarketHive</h1>
       <div class="chat-container" id="chatContainer">
       </div>
       <div class="input-container">
           <input type="text" id="userInput" placeholder="Type your message..." autocomplete="off">
           <button onclick="sendMessage()">Send</button>
       </div>
   </div>

   <script>
       const WEBHOOK_URL = '[ insert webhook URL Here]';
       const chatContainer = document.getElementById('chatContainer');
       const userInput = document.getElementById('userInput');
       
       // User data
       const userData = {
           name: "Jake",
           userID: "274828"
       };
       
       // Track the current webhook URL
       let currentWebhookUrl = WEBHOOK_URL;
       
       // Add initial bot message
       addMessage(`Hi ${userData.name}, What can I help you with today; learning, trading, or investing?`, 'bot');
       
       function addMessage(text, sender) {
           const messageDiv = document.createElement('div');
           messageDiv.classList.add('message', `${sender}-message`);
           messageDiv.textContent = text;
           chatContainer.appendChild(messageDiv);
           chatContainer.scrollTop = chatContainer.scrollHeight;
       }
       
       async function sendMessage() {
           const message = userInput.value.trim();
           if (!message) return;
           
           addMessage(message, 'user');
           userInput.value = '';
           
           try {
               const response = await fetch(currentWebhookUrl, {
                   method: 'POST',
                   headers: {
                       'Content-Type': 'application/json',

                   body: JSON.stringify({
                       message: message,
                       name: userData.name,
                       userID: userData.userID
                   })
               });

               if (!response.ok) {
                   throw new Error(`HTTP error! Status: ${response.status}`);
               }

               const rawText = await response.text();
               console.log('Raw response:', rawText);

               try {

                   console.log('Parsed response:', responseData);
                   
                   // Check for Wait node's webhook URL
                   if (responseData.resumeUrl) {
                       currentWebhookUrl = responseData.resumeUrl;
                       console.log('Switching to resume URL:', currentWebhookUrl);
                   } else {
                       // Reset to initial webhook if no resume URL
                       currentWebhookUrl = WEBHOOK_URL;
                   }
                   
                   if (responseData.question) {
                       addMessage(responseData.question, 'bot');
