A lot of error message: "_handleRequest(): request handler not found"

[eos1d3]

Using current release, I keep seeing a lot of this error repeatedly even I do not enable ESPALEXA_DEBUG.

[E][WebServer.cpp:617] _handleRequest(): request handler not found

This problem may also happen in previous release. What is this error? All devices are all working normally though.

Myself, I have never seen such an error. It seems to merely indicate to not have found a handler for the incoming request and thus calling onNotFound(), which is nornal behavior.

Probably you have a debug level other than None set in the Tools menu. Or it is a built-in debug function of ESPAsyncWebServer you can enable in the library...

I just use EspalexaFullyFeatured example with ESP32 without much change. And I do not use ESPAsyncWebServer.

The beginning is:

include

#ifdef ARDUINO_ARCH_ESP32
#include <WiFi.h>
#else
#include <ESP8266WiFi.h>
#endif
#include <Espalexa.h>

I use PlatformIO, the platformio.ini does not define debug level too:

[env:esp32dev]
platform = espressif32
board = esp32dev
monitor_speed = 115200
framework = arduino
lib_deps =
  Espalexa@247afb17b4

I am using the same EspalexaFullyFeatured file and never saw this error from previous versions of the library. And I do not change it after using latest version. And now I keep seeing this error occurs repeatedly in serial terminal.

Any information I can provide for you to check?

I will try to create a new project with the library to see if the current project has problem.

Below is the compile message:

DEBUG: Current (esp-prog) seems to be the culprit. I am unsure though how one would go about disabling it...

I'm also seeing these messages printing on my serial.

I am also seeing similar messages [E][WebServer.cpp:633] _handleRequest(): request handler not found [E][WebServer.cpp:633] _handleRequest(): request handler not found [E][WebServer.cpp:633] _handleRequest(): request handler not found

once I read that it could be due to the version of some library or the software itself, that time I was able to delete the error but I have not been able to find it again
