ESPhome lambda: Problem with string conversion

May I please ask to explain why I am getting error in lambda? I try to update text sensor. if I put string as parameter then it compiles fine:

        String url = "http://api.openweathermap.org/data/2.5/onecall?lat="+String(id(latitude).state)+"&lon="+String(id(latitude).state)+"&appid=9744aad7b7----d8c0d&exclude=minutely,daily,alerts";
        id(last_url).publish_state("test");

but when I put url instead of test I get error:

        String url = "http://api.openweathermap.org/data/2.5/onecall?lat="+String(id(latitude).state)+"&lon="+String(id(latitude).state)+"&appid=9744aad7b7----d8c0d&exclude=minutely,daily,alerts";
        id(last_url).publish_state(url);

the error:

Documents/blinds-brain-gps.yaml: In lambda function:
Documents/blinds-brain-gps.yaml:271:36: error: no matching function for call to 'esphome::template_::TemplateTextSensor::publish_state(String&)'

Banging my head to resolve it…

solved it with this:

      char urlch[200];
      url.toCharArray(urlch,200);
      id(last_url).publish_state(urlch);
