I have a button on a case that when selected, triggers an https.requestSuitelet.promise method that runs a Suitelet in the backend to create a quote. The Suitelet will return a response of completed or failed. The first time this button is clicked, the console shows "listener indicated an asynchronous response by returning true, but the message channel closed before a response was received.", but the button works fine after. How do I prevent this error?

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like the issue you're facing is related to the asynchronous nature of the Suitelet call. When the button is clicked, the Suitelet is called and starts processing, but the response is not immediately available. This can cause the error message you're seeing, as the listener is expecting a response that isn't there yet. One way to handle this is to change the order of operations. Instead of waiting for the Suitelet to finish processing before returning a response, you could immediately return a response to the UserEvent and then let the Suitelet continue processing in the background. This way, the listener isn't left waiting for a response that isn't ready yet. Here's a rough idea of how you could implement this: 1. UserEvent triggers and sends data to the Suitelet. 2. Suitelet immediately returns a response (e.g.,

response.write('Processing...')

). 3. Suitelet continues processing in the background. Another approach could be to use a client script to show a loading message or some other indication that processing is happening. This could help to prevent the user from clicking the button again before the Suitelet has finished processing. Remember, this is just a suggestion based on the conversations provided and might need to be adjusted to fit your specific use case. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
