I’m a little confused. The repository you’re building from doesn’t have a hugo site source in it. I’m not exactly sure what these lines mean…
9:31:17 PM: Error running command: Build script returned non-zero exit code: 255
9:31:17 PM: failed during stage 'building site': Build script returned non-zero exit code: 255
but I’m guessing it’s hugo throwing an error because it can’t find a valid directory config.toml and directory structure to build the site.
