Redundant try-catch block?

In this video, if we already implemented a try-catch block for a parsing exception which would be thrown if there is an invalid JSON object, does this become redundant now that we have this error message for an unexpected https response, since when we look for an invalid profile it should return 404, and it won't bother with the parsing try-catch block

These are different kinds of errors.

For example, what if your request was for a valid profile, but due to some internal error the server returned an invalid JSON object?

Asynchronous flow's errors are not caught by the external try-catch.
