        # This multiline regex is used to detect a JSON string.
        # It captures any block that starts and ends within two open and closed curly braces `{}`
        #
        # The major limitation to this regex is:
        # - It does not validate the contents of the curly brace. Therefore it can also catch incorrect JSON: {{hello:world}}
        # - The regex breaks when a JSON string is nested 3 levels deep or more. For example: {"hello": {"x": {"test": {}}} }
        #   Because of this, Logs should be limited to a maximum of 3 levels.
        #   This limit can be increased by adding more capturing blocks: (?:[^{}]|\{[^{}]*\})
