• Stringifying the element is wrong and unnecessary.
• type="text/javascript" is also unnecessary as this is the default.
• <-- Don't bother with self-terminated syntax.

The latest version of @azure/web-pubsub should've removed the "URL" dependency. Fixed with https://github.com/Azure/azure-sdk-for-js/pull/15300

I got assistance from Netlify forums. Basically the following changes needed to be made:

1. The fetch request -- line 43 in the calling code (script.js) -- needed to be changed to

Probably you meant to pass "brand" or "data" to db.query() instead of res. So try "[brand, id]" or "[data, id]".

I think the parameters you pass in the second array should have a toString() method. This is because they are needed to be embedded into sql string. I came up with this idea using the stack trace of the error. The sqlstring library is trying to escape the parameters(for things like preventing sql injection), and there, it must be calling toString() on a parameter if it's not a string.

After a day's review of the project, I was:

• importing a class from the middleware that was using a library of the backend.

• using a library from the backend in the frontend

To fix the issues also complies with best-practices.

I have split the class in the middleware into two classes: one for the frontend, one for the backend. I have refactored the code so that the backend library was not necessary on the frontend. I ended up just fixing two files. And all the errors dissapeared.

So if you encounter something similar, double check whether or not you use some backend libraries/classes in your frontend.

Here should be not calls, but funcs

Your form is submitting automatically because of the way you've set the event handler. The .addEventListener() API requires a reference to a callback function as the second argument. But you passed a function call with arguments like this:

loginButton.addEventListener("submit", submitLogin(loginData));

You have two choices to fix this:

1. Pass a reference.
   • This will require loginData to be available to the handler in some other fashion.

loginButton.addEventListener("submit", submitLogin);

1. Enclose the call within a function expression:

loginButton.addEventListener("submit", ()=>submitLogin(loginData));

Option 2 is generally preferred when needing to pass parameters to the handler. But you'll see below, for you, option one is the way to go.

The leads to the next problem - submitLogin() function itself.

Just try this. I did not test this. but the error is in htmlInfo = require("../template/infoString")

module.exports = { infoHtml: () => { return '

assign the functions and values we want to export to an exports property on module:

const { infoHtml } = require('./user'); console.log( ${infoHtml()} );

A function that is used in the same module it was declared cannot be spied mocked, unless it's consistently as a method of some object, which is cumbersome and incompatible with ES modules:
