AP Mode - esp_wifi_set_config throwing error

[Amorphous]

Creating a program to start the ESP8266 in AP Mode. But everytime I run it the function esp_wifi_set_config throws an error

Error :

}

Can anyone please point to my mistake here?

Hi, you should run 'esp_netif_init()' prior to calling 'ESP_ERROR_CHECK(esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &wifi_event_handler, NULL));' the should fix the problem.
