Divya updated AVRO-3064:
------------------------
    Description: 
Hello,

 

We are looking for documentation on how a fixed value can be used with null.

We are using avro-1.8.0 and trying to generate a Decimal value with the help of 
JSONDecoder for schema:

        {
            "name": "exacAmt",
            "type": [
                {
                    "type": "fixed",
                    "name": "exacAmt",
                    "size": 16,
                    "logicalType": "decimal",
                    "precision": 38,
                    "scale": 2
                },
                "null"
            ]
        }

But we are getting an exception:

_Message: Unknown union branch fixed_
 _Line | Method_
 _->> 445 | readIndex in org.apache.avro.io.JsonDecoder_

 

Please advise how can this issue be resolved.
