Description

If a union type of null and logical type of uuid is used, Avro will try to decode the object as a UUID and create a TypeError exception, which is not caught.

Example Schema:

{
  "name": "userId",
  "type": [
    "null",
    {
      "type": "string",
      "logicalType": "uuid"
    }
  ]
}

if the example schema is given a userId of None then the application will stop with an uncaught exception.
