XPath always invalid

[xxluke]

Expected Behavior

XPath filters should return a detected value

Actual Behavior

The "Live Preview" shows "Invalid XPath query: [...]" and the tag doesn't work.

Reproduction Steps

The response where I want to use XPath looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Process timestamp="2024-09-25T13:16:26+00:00">
	<Request BusinessID="2d35aaad-018c-4710-93fa-0f642ce1febb">
		<Confirmation/>
	</Request>
</Process>

I used http://xpather.com/ to verify my XPath, which is //Request/@BusinessID and works there.

I also tried other queries and the only one where I didn't get the error was /*.

Is there an existing issue for this?

I can confirm this issue. This worked prior to updating my client last week (I have automatic updates disabled to prevent this sort of thing.) Using the recommendation from @xxluke I also verified the XPath filter on https://xpather.com.

This breaks my entire collection. How is this still broken for nine months?

I had the same issue on v 11.2.0, reverted to v 11.0.2 and it worked as intended
