How to Resolve GPIO Pin Configuration Failures for DHT22 Sensor on AVR32UC with Zephyr OS?

Hey guys, still on my DHT22 Sensor Integration. who knows how I can configure GPIO pins on the AVR32UC for a DHT22 sensor using Zephyr OS, and how can I resolve GPIO pin configuration failures, which prompts this error message: Failed to configure GPIO pin.
I have been able to define the GPIO pin for the DHT22 sensor and attempt to configure the GPIO pin as input yet the error.
This is my code snippet:
#include <zephyr.h>
#include <device.h>
#include <drivers/gpio.h>

#define DHT22_PIN 2
#define GPIO_PORT DT_LABEL(DT_NODELABEL(gpio0))

const struct device *gpio_dev;

void main(void)
{
    gpio_dev = device_get_binding(GPIO_PORT);
    if (!gpio_dev) {
        printk("Failed to bind GPIO device\n");
        return;
    }

    if (gpio_pin_configure(gpio_dev, DHT22_PIN, GPIO_INPUT) < 0) {
        printk("Failed to configure GPIO pin\n");
    }
}

The GPIO pin should be correctly configured for the DHT22 sensor, allowing for proper sensor communication, If the implementation is successful.
