HttpNode doesn't sent body

[BunnySalsa]

Trying to sent simple http post request to local rest service using HttpNode. The only thing that has been added into docker-compose.yml is

        extra_hosts:
            - host.docker.internal:host-gateway

So request to localhost sended to http://host.docker.internal:8080
In container logs I can see that body instead of my x-www-form-urlencoded params sent 0=&1=&=2&3=
Problem is similar to query params
Flow has been saved before execution
