ESPAsyncWebServer using DHT22

[fazlur142]

Hey can anyone tells me why this error message show on me?

d:\Kuliah\Magang\Project Mentor\libraries\ESP_AsyncTCP\src\ESPAsyncTCPbuffer.cpp:27:10: fatal error: debug.h: No such file or directory
#include <debug.h>

I moved your topic to a more appropriate forum category @fazlur142.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

We need more info.
Can we have the whole error message and the code?

[fazlur142]

Ohh yeah sure
