In a try/catch, why would this print {} as the details?

catch (e) {
        log.error('Error:', e);
      }

Title: "Error:" Details: "{}" I thought catching e would catch the error message, but it seems as if there is no error message but it still failed?

code looks fine... is it possible there's a

throw

somewhere in the try that doesn't actually throw anything?

There are no throws, I opened up debug logging to see if it happens again, I tested myself and it was fine so I am waiting for someone else to encounter the issue as it happened 17 times today. Strange as it has never happened before
