ReferenceError: URL is not defined

[Paul Armstrong]

Inside of a Google Workspace Add-on, I am trying to use a URL class as follows:
new URL("https://google.com");
But this throws a ReferenceError: URL is not defined

If the code ran in the user's Browser, this would not happen. But server-side in Google's walled garden and this class is not present.

If this was Java, I'd make sure the class was on my path (in a .jar) and import it.

what is the best solution in google-apps-script? 

Thank you!

If you are developing a Workspace add-on (Gmail, Calendar, Drive), you are limited to using the cards and cardservice. If you are making an Editor add-on (Sheets, Docs, Slides, Forms), then you might be able to do what you want while serving HTML.
Otherwise, you should still be able to use the built-in UrlFetchApp instead of creating your own Class.

Thank you!

That is a perfect solution. Plus, it also explains the scope of what is possible and what is not.
