This was probably just one error, which was emitted for several history entries when someone was looking at page history.

https://pt.wikibooks.org/w/index.php?action=history&title=Utilizador_Discuss%C3%A3o%3ARaylton_P._Sousa was the culprit but it works for me. There are some revision-deleted entries so maybe it's related to that, although how could four entires cause ten errors?

In any case, Flow is not actively supported and the impact here is minimal (one-off error which didn't cause any user-visible problem) so fixing this won't be prioritized.

I'm not sure there's any relationship. One happens on a page move, the other on a plain history view (and the page it happens to was never moved).
