Cannot read property 'name' of null

I cannot initialize this plugin. Here is the output and my config file - any ideas anyone? I'm using macos 10.15. Thanks!

I have removed securityCode, pin, and username.
Seems to relate to this line in the code

It seems like the "auto-ip-address-detect-feature" of the gateway failed. Try specifying the IP address manually. Modified the code to respond with an appropriate message.

    getHostName() {
        return new Promise((resolve, reject) => {

            if (this.config.host != undefined)
                resolve(this.config.host);
            else {
                this.log('Discovering gateway...');

                Ikea.discoverGateway().then((discovery) => {
                    if (discovery && discovery.name) {
                        this.log('Discovered host "%s"', discovery.name);
                        resolve(discovery.name);
                    }
                    else {
                        reject(new Error('Cannot discover gateway address. Sorry, you have to enter the IP address yourself in ~/.homebridge/config.json.'));    
                    }

                })
                .catch((error) => {
                    reject(error);
                })
            }
        });        
    }
