Error compiling for board esp32 Dev Module

Question

Error compiling for board ESP32 Dev module.

Hello! I'm here seeking your assistance please. I have been working with arduino and esp32 module for posting some data to a dedicated platform. However, upon modifying the data to json supported format as shown below the error started to emerge.

//----------------------------------------GET HTTP Request
  // Prepare POST request data
  DynamicJsonDocument doc(1024);
  doc["dht_sensor_API_KEY"] = apiKeyValue;
  doc["temperature"] = temperature;
  doc["humidity"] = humidity;

  // Serialize data to JSON
  serializeJson(doc, httpRequestData);
    
  // Send POST request
  httpResponseCode = http.POST(httpRequestData);

I'm working on a personal project that involves sending DHT sensor data toa dedicated hosted platform with telemetry data packaged in JSON format using DynamicJsonDocument.as shown in my actual code snippet below

Compiling this with all necessary connection details appended I get this error:
