It looks like there was a network issue during the build, breaking the build. Since the tag is made before the build, it's not possible to retry.

build failed: exit status 1: go: downloading golang.org/x/mod v0.27.0

This seems to be a networking error that's out of our control...

Can we set GOPROXY to "proxy.golang.org,direct" ?
