Comment 1 for bug 2071485

Hi Mike, thanks for your report.

"Top-level keys" refers to the outer most keys, as listed in the documentation section of the same name[1]. I can agree it's a little vague, but there should be some more error messaging pointing to a more specific issue.

Could you share the contents of /var/log/installer, the example autoinstall you are trying to use, and how you are delivering the autoinstall configuration?
