* fix: start node strem asyncly * fix: headers value may be a list * fix: simply destruct on finish/error * fix: class may destruct immediately after subscribing "data" * fix: send meaningful error * fix: must always provide a response body * fix: handle the case when one write can not write all data * fix: handle connection error
