[BUG]: ParquetSerializer.DeserializeAsync (fasm.Field is null)

How to reproduce?

I used the following to create a Parquet file from a List (same behaviour with a class).
await ParquetSerializer.SerializeAsync(sortedTicks, parquetFilePath);

However if I immediately try to load the file it appears full of default values.
IList ticksP = await ParquetSerializer.DeserializeAsync(parquetFilePath);

Tracing through the code in the debugger reveals an exception being thrown from ParquetSerializer:279 because this comparison returns false : fasm.Field.Equals(dataField).
I can see this is because the dataField.SchemaElement is set to a valid element, but in fasm.Field is null.

Here is a sample file which will trigger the error when read: https://1drv.ms/u/s!AhDUHssG2nbYmoM7f0vBU3Lm8-Thow?e=TPGsP9

The Floor app can display the file fine.

private static int tickSize = 100000; // TODO - Look this up for the specific instrument
