Draft: Fix behavior of getHttpString helper

What does this MR do and why?

Fix the behaviour of getHttpString helper, so it is aligned with the current modal.

The helper function should return an empty string if the result does not include all the following values:

• Method or status code
• URL or reason phrase
• Headers

Screenshots or screen recordings

Screenshots are required for UI changes, and strongly recommended for all other merge requests.
