Error Handling: How to maintain detailed error message

I have a main workflow and an error workflow to catch errors and send a slack message.

Something I’m struggling with is actually maintaining all the details of an error when I use “Continue” or “Continue (using error output).

When I use “Stop Workflow” on error, I get a detailed error message such as this:

When I use the other options, it only logs “400 - “““ and no subheading.

Is there a way for me to keep or get this information within an error workflow? Other than making an error workflow for the error workflow :sweat_smile: .
