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.
