This message is not present in any of the PMG scripts.

You get this issue on build.func, whats your pveversion?

version="$(pveversion)"
echo "Current PVE version: $version"
if echo "$version" | grep -Eq "^pve-manager/8\.[1-3](\.[0-9]+)*"; then
  echo "✅ Version is supported (8.1 to 8.3)"
else
  echo "❌ Version is NOT supported"
fi
