Http.request.headers.names Error

According to this online document the firewall rule expression “http.request.headers.names” is an available rule. However I see this error when i try to change the expression mode back to expression builder.

Does this mean this specific expression in invalid or not available?

The expression builder does not support all the fields the expression editor does. You will have to leave that firewall rule in the expression editor.
