Azure logic app's try-catch specific error capture does not work

Question

I am creating an azure logic app workflow with try & catch scope to capture specific exception message happens in one of actions within try scope.

As per the documentation, I am filtering Failed status of result('try') but still getting generic message " An action failed. No dependent actions succeeded." even when I try to capture body('Filter_array')?[0]?['error']?['message']

I followed this article & azure documentation as well but no luck: https://www.tech-findings.com/2022/06/Exception-Handling-in-Logic-app.html
