        return true; // Indicates successful device additions after all devices are processed

module.exports = {
    addingDevice: addingDevice
};

Im trying to add device using the node @chirpstack/chirpstack-api, but i got

Error at adding device: Error: Incorrect arguments passed

Anything that i might miss? Thanks in advance!

Did you try creating the device without adding the keys?

It seems setNwkKey (use AppKey to set the field) is mandatory, at least with Python. I’ve stopped with JS as it seems not possible to add tags.

#3 
async function addingDevice(server,apiToken,deviceList,applicationId,deviceProfileId){

    //check if device is not an array
    if (!Array.isArray(deviceList)) {
        deviceList = [deviceList];
    }

    for (const deviceData of deviceList) {
        try {
            //setting up the device
            const req = new CreateDeviceRequest();
            const device = new Device();

            device.setDevEui(deviceData.devEUI);
            device.setName(deviceData.name);
            device.setApplicationId(applicationId);
            device.setDeviceProfileId(deviceProfileId);
            device.setDescription("Registering device via API");
            device.setIsDisabled(false);
            device.setSkipFcntCheck(false);
            device.setIsDisabled(false);
            req.setDevice(device);

            //setting up the device key
            const keysReq = new CreateDeviceKeysRequest();
            const keys = new DeviceKeys();

            keys.setDevEui(deviceData.devEUI);
            keys.setNwkKey(deviceData.appKey);
            keys.setAppKey(deviceData.appKey);
            keysReq.setDeviceKeys(keys);

            //adding the device and the device key
            const channel = await new DeviceServiceClient(server, grpc.credentials.createInsecure());
            const metadata = await new grpc.Metadata();
            await metadata.set("authorization", "Bearer " + apiToken);
            await channel.create(req, metadata, (err, resp) => {
                if (err !== null) {
                    console.log("Create err:", err);
                    return;
                } else {
                    console.log("Create Device success: " + deviceData.name);
                }
                channel.createKeys(keysReq, metadata, (err, resp) => {
                    if (err !== null) {
                        console.log("CreateKeys err:", err);
                        return;
                    } else {
                        console.log(
                            "Create DeviceKey success: " + deviceData.name
                        );
                    }
                });
            });
        } catch (e) {
            console.log("Error at adding device key", e);
            return response.status(500).send(`An error occurred: ${e}`);
        }
    }
    return true;
}

Yes, I forgot the nwk key and how there is still an error occurring. But somehow the code up here works perfectly. I hope this piece of code can help anyone who’s going through this.
