There was an error? really? wow, never would have guessed, very informative, much BLOODY THANKS.

You don’t say

Another reason to make your own node.js web server.

It's a server error, you don't need to know what happened.

If it's your server, check the logs.

The main students' platform in our uni sometimes raises a "Generic error" when we click on items on the screen.
"Generic error"... Looks like none thought about defining detailed exceptions.

I do this all the time when working with Firebase, the client does not need to know what exactly happened. I just change the wording for each error slightly so it's easier to find when someone decides to report it (which they should not do as I probably already know about the error)

I see you're a man of insomnia as well ;)
