X750 image builder issues

HI we are trying to build a custom image for the x750 based on openwrt 19.09.7 and gl-inet v3.203

but its failing due to missing packages and repos in the repositories.conf file.

as all the repos fw.gl-inet.com are now s3 buckets we cant see can we take the files from download.gl-inet.com and if so is there a complete list of the needed correct repos?
