Compare view shows JSON parse error for empty payloads

[georgidhristov]

Description

Compare view displays a Failed To Parse JSON warning even when both request bodies are empty.

This creates unnecessary visual noise and suggests an error exists when the payloads are actually empty.

Expected

Empty request or response bodies should be handled gracefully without displaying JSON parse errors.

Possible behavior:

• show (empty) only
• hide parse warning for empty content

Actual

The compare UI displays:

Failed To Parse JSON
