Server Side Fingerprinting - Message vs Value?

1

Does anyone know what the “value” matcher actually matches against?

In a JS project, I tried setting up a pattern match against exception messages, but it didn’t match content in the message that showed up after a newline. Not sure if this is expected or a bug.

Message Line 1
Message Line 2
    stack trace...

Was wondering if using value: instead of message: would maybe work, but I have no idea how the “exception value” is defined.

Thanks in advance to anyone who might have some more insight!

Actually, based on this:

If value is the exception message from the JS SDK, what is message: matching against?
