Solved 👍: Apps Script deployed as a Web App returns 404 error

The problem

You deployed your Google Apps Script code as a Web App. However, when you open the web app's URL, it returns a 404 error.

When you deploy your script as a Web App, you will receive a URL like the following:

Sometimes the URL will contain /u/1/. If you see this in the URL, please remove it.

Next, if you deployed the script from within a G Suite domain. Please add /a/<your domain name> right after

Now, try opening the URL in your browser. Your web app will no longer return a 404 error and you should be able to see the output generated by your web app.
