Does anyone know what is happening with this error?

String requestURL = String(apiURL) + "?key=" + apikey + "&q=" + city;

 
  HTTPClient http;

  
  int httpCode = http.begin(requestURL);
  int httpResponseCode = http.GET();
  Serial.print("error code: ");
  Serial.println(httpResponseCode);
  if (httpResponseCode == 200) {
   
    String payload = http.getString();

    
    StaticJsonDocument<384> doc;
    DeserializationError error = deserializeJson(doc, payload);
    if (error) {
      Serial.print("deserializeJson() failed: ");
      Serial.println(error.c_str());

      return;
    }
    JsonObject current = doc["current"];
    int current_humidity = current["humidity"];
    Serial.print(current_humidity); 
    http.end();
}

Can't read data from JSON file, and flush seems to report an error again.

What is your arduino board? Do you use an Ethernet shield or module?

my board is esp32dev,i used board WiFi connect internet.

You mean this error?

Looks like that's the standard HTTP response code?

So it's not an error at all!
