/rest/api/3/serverInfo endpoint started to return "invalid URL error"

This endpoint was working fine for a year or so, but it started to return an error when invoked from the Forge backend ( ‘Invalid URL: /rest/api/3/serverInfo’ ). Version 2 also returns the same error. It works fine if I paste the URL directly into the browser. Multiple customer sites have the same error, it is not site-specific. Is there any other endpoint we can use to get the customer’s site URL? We can get the site URL from the context variable for normal Forge method invocations, but it is not available when the method is triggered from the scheduler or webtrigger?

I think this was a temporary issue of the Forge platform, and it is now fixed by itself.
