> Currently, the C++ JSON table reader does not support the Arrow FixedSizeList type.
> When the Arrow schema is not inferred but supplied to the parser, it should attempt to turn JSON arrays into an Arrow FixedSizeList if the schema dictates this for specific fields.
> This currently results in the JSON table reader returning an error, e.g.:
> {code:java}
> JSON conversion to fixed_size_list<item: uint64 not null>[12] is not supported{code}
