Basic Infos

Hardware

WiFimanager Master

Esp8266/Esp32: Esp32

Hardware: ESP32 wroom 32d

[env:esp32dev]

Core Version: vs code PIO

Espressif 32 6.8.1

[env:esp32dev]
platform = https://github.com/platformio/platform-espressif32.git
board = esp32dev
framework = arduino

Description

After compiling and uploading to ESP32 using VS Code PIO IDE, when entering the Wi-Fi configuration page, the serial output shows the following error:
[18356][E][WebServer.cpp:638] _handleRequest(): request handler not found

When using Arduino to upload, it works normally.
