Error when running embedding of pages

Issue Description

Hi,
I have started embedding process in CLI.
Every few lines I see following error

Is htis something I should be worried about? How can this be fixed?

The issue is caused by the indexmenu plugin. Since it's a warning only, it probably has no effect on the page rendering and the embedding generation. In any case it would need to be fixed in the indexmenu
