wixChat_onMessage does not trigger at all

Hi! I think you have your code in the wrong place - it should be in an events.js file.

Here’s an example I have from integrating tensorflow into Wix Chat - you can ignore that part of the code, but this file should give you a clue of how to structure this properly

github.com/amandamartin-dev/velo-tensorflow

events.js

main

import {predict} from "backend/toxicity.web.js"

export function wixChat_onMessage(event) {
    if (event.direction === "VisitorToBusiness") {
        predict(event.payload.text, event.channelId)
    }
}

and here is where i’m creating the message and sending it back to the chat

github.com/amandamartin-dev/velo-tensorflow

toxicity.js

main

//This code is for use in a web.js file in Wix Studio or Classic Wix editor
//you will also need the events.js file

import * as toxicity from '@tensorflow-models/toxicity';
import { Permissions, webMethod } from "wix-web-module";
import wixChatBackend from 'wix-chat-backend';
require('@tensorflow/tfjs');

let model;
let modelPromise;
const loadModel = () => {
    const includedLabels = ["toxicity"];
    modelPromise = toxicity.load(0.9, includedLabels)
};

loadModel();

export const predict = webMethod(
    Permissions.Anyone, async (inputs, channelId) => {
        console.time("Prediction time")

This file has been truncated. show original

events.js is a reserved file name in Wix/Wix Studio - so it must be structured and named this way or it will not fire

Here is some more information and a video on how to use backend events that may help as well About Backend Events
