nRF5340: Undefined Reference to __modem_pipelink_142_user_pipe_0 in Cellular Modem Example

Issue

I am working on an nRF5340 and trying to integrate the cellular modem example into my project. However, I encounter the following linking error:

zephyr/drivers/modem/modem_at_shell.c:147: undefined reference to `__modem_pipelink_142_user_pipe_0'

I give you the details of my project configuration in the next part of the post. I don't really understand what I can change to have the pie set up. Could you help me ?

Device Tree (DTS) Overlay Configuration

Here is my DTS overlay where I define the modem under UART3:

&uart3 {
    status = "okay";
    compatible = "nordic,nrf-uarte";
    current-speed = <115200>;
    pinctrl-0 = <&uart3_default>;
    pinctrl-1 = <&uart3_sleep>;
    pinctrl-names = "default", "sleep";

    modem: modem {
        compatible = "quectel,bg9x";
        mdm-power-gpios = <&pca3 14 (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN | GPIO_PULL_UP)>;
        mdm-reset-gpios = <&pca3 2 (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN | GPIO_PULL_UP)>;
        status = "okay";
    };
};

/ {
    aliases {
        modem = &modem;
    };
};
