Query for dictionary keys inside a collection in mixed doesn't work

[nirinchev]

I have the following query: ANY oneAny[*].foo.@keys == 'child' which throws the following exception:

The keypath following 'ANY' must contain a list. Error code: 1009.

oneAny is a mixed property. In my test, it contains a collection, where one of the elements is a dictionary. In 2 test objects, the value for foo is a string and in 1 test object, the value is a dictionary with one of the keys being child. I would expect the query to match the 3rd object.

@nirinchev A quick question: If you remove ANY, does it then work?

[nirinchev]

Hey @jedelbo, yes, removing ANY fixes it.

So in this case you could say that ANY is redundant, but I found other cases where it made sense, so a fix was required.
