Domain mappings are not available in the region of the selected service

Published a website. When I tried to map it to my own domain. It popped out an error: Domain mappings are not available in the region of the selected service. Website was built in US west1. But the domain is in US West2? And this is not the limited 10 regions. But there is no option for me to change this? How can I correct this error.

Google not allowing an easy way to do domain mapping anymore, I don’t even see the option to download the project anymore. It was fun while it lasted. Moving on to something better

Thanks. I figured it out by using Netlify.
