Description

4xx and 5xx status codes are not properly handled at the Catalyst level.

Issue

Current handling of error status codes seems incorrect.

let status = matches.length && matches[0].match.path === "*" ? 404 : 200

This does not account for actual error codes being passed.

Proposed Solution

Ensure proper use of the errorCode prop for handling status codes:

let status = errorCode || (matches.length && matches[0].match.path === "*" ? 404 : 200)
