[Issue]: Error when all fields are optional in AVRO

[RaulBejaranoSngular]

What happened?

There is an exception when all fields are optionals. That happens because there is no field marked as shouldProcess. I think the solution is check if all fields are optionals and if so check the last one as shouldProcess.

Schema:

{
  "type": "record",
  "name": "FirstSchemaStreamingPOCTest",
  "namespace": "test",
  "fields": [
    {
      "name": "randomNumber",
      "type": [
        "null",
        "string"
      ],
      "default": null
    },
    {
      "name": "randomCode",
      "type": [
        "null",
        "string"
      ],
      "default": null
    }
  ]
}
