Really it could be as easy as you’re not connected to the internet. Once WiFi is turned on, open the network utility and click on apple support which will allow you to pull up a web browser. Then it’ll prompt you for your WiFi password in order to connect to the internet. Once connected, back out and go back to Mac OS reinstall. It shouldn’t show the no bag error any more. Worked for me, hope this helps.
