getMissingItems returns just missing items from crafting task; it ignores missing fluids.
But there is not getMissingFluids() - please ass information about missing fluids as well.

This is a duplicate of #1907

Sorry, that one had no description and title was not exactly what I had in mind.
I just reported that there is no way to check if request will fail or not; fluid autocrafting works as long as fluids are there :-)

No problem, I understand.
