Crash with simple code

[gergocs]

With this simple code:

    PsychicHttpServer server = PsychicHttpServer();
    Serial.begin(9600);
    WiFiClass::mode(WIFI_AP_STA);
    WiFi.begin(SSID, PASSWORD);
    while (WiFi.status() != WL_CONNECTED) {
        delay(500);
    }

    delay(1000);

    server.listen(80);

the ESP crashes.

Stack memory�Guru Meditation Error: Core  0 panic'ed (Load access fault). Exception was unhandled.

(ESP32-C6-devkitM-1) If i delete the server.listen(80) line then it works. Also it crashes instantly doesn't wait for delay(1000)

Increase the stack size of your task

[mathieucarbou]

@gergocs : can you please decode the stack trace with your elf file ? => https://maximeborges.github.io/esp-stacktrace-decoder/

Also it crashes instantly doesn't wait for delay(1000)

That is weird... Maybe not a Psychic issue then ?

Please upload your ino file and tell us which version you are using. I have a C6 at home so I should be able to check.

[gergocs]

I'm using the main branch so the latest.

I'm using platformio with arduino so I have main.cpp main.cpp:

#include <PsychicHttpServer.h>
#include <PsychicEventSource.h>
#include <WiFi.h>

PsychicHttpServer server = PsychicHttpServer();
PsychicEventSource eventSource = PsychicEventSource();

void setup() {
    WiFiClass::mode(WIFI_STA);
    WiFi.begin(SSID, PASSWORD);
    while (WiFi.status() != WL_CONNECTED) {
        delay(500);
    }

    delay(1000);

    server.config.max_uri_handlers = 20;
    server.listen(80);
}

void loop() {
}

(The SSID and password are created with #define ""

I'm sure you left out something important

[gergocs]

platformio.ini:

[env]
platform = espressif32
framework = arduino
build_src_filter =
    -<*>
[env:main]
build_src_filter = +<tmp>
board = esp32-c6-devkitc-1
build_flags = -fexceptions
build_unflags = -fno-exceptions
lib_ldf_mode = deep
lib_deps =
    https://github.com/hoeken/PsychicHttp.git

tmp folder only contains a main.cpp.

[gergocs]

Update: After removing this line from esp_err_t PsychicHttpServer::_start() methode

  // Register handler
  ret = httpd_register_err_handler(server, HTTPD_404_NOT_FOUND, PsychicHttpServer::notFoundHandler);
  if (ret != ESP_OK)
    ESP_LOGE(PH_TAG, "Add 404 handler failed (%s)", esp_err_to_name(ret));

it doesn't crash, but now if I try to add a new handler for the server it crashes. It looks like the issue is with httpd_register_uri_handler and httpd_register_err_handler Also one thing to add is the server property is not null so it is initialized.

[gergocs]

Update: I have deleted platformio and reinstalled it. And some kind of reason it works. Don't ask me why.

[hitecSmartHome]

Probably some cache issue. First thing I do in these mysterious cases is to do a full clean and restart ws code. If it does not help delete any cache folder and pio folder
