> I have cloned the GitHub repo and built the C# solution (Avro.dll) since
> 1.11.2 with the JsonEncoder has not yet been released as a Nuget package.
> A schema with a nested record works fine.
> A schema with a nested array of record throws the above exception.
> The BinaryEncoder however is able to produce the binary Avro with the same
> schema.
> I have attached the schema.
> My code is a simple C# .NET console application.
> Program.cs is also attached along with the schema data model that was
> generated using CodeGen.
