Esphome http_request after last update didn't work anymore

Hellow,

After last update of esphome, I get this error with http_request:

here is a part of my yaml:

 - interval: 1s
   then:
      - http_request.get:
          url: http://192.168.1.201/sensor/power_consumed
          capture_response: false
          on_response:
            then:
              - lambda: |-
                  json::parse_json(id(http_request_data).get_string(), [](JsonObject root) {
                      id(afgenomenpower).publish_state(root["value"]);
                  });

and I get this errror:

/config/esphome/boilersturing.yaml: In lambda function:
/config/esphome/boilersturing.yaml:586:43: error: ‘class esphome::http_request::HttpRequestArduino’ has no member named ‘get_string’
json::parse_json(id(http_request_data).get_string(), (JsonObject root)

Wherever you copied that code from seems not to be working anymore.
See HTTP Request — ESPHome for a working example
