There is one issue however I am stuck on: the tests for empty sets ("typed
aggregate: empty") seem to be casting to nulls from options, resulting into the
following:
Decoded objects do not match expected objects:
expected: WrappedArray([0.0,0,NaN,None,None,None,None])
actual: WrappedArray([0.0,0,NaN,[null],[null],[null],[null]])
This doesn't happen to non-empty data sets. Does anyone have a clue?
