             Summary: avro::Exception string gives the incorrect message
                 Key: AVRO-2186
                 URL: https://issues.apache.org/jira/browse/AVRO-2186
             Project: Avro
          Issue Type: Bug
          Components: c++
    Affects Versions: 1.8.2
         Environment: {code:java}
$ uname -a

            Reporter: Anubhav Siddharth


When a field specified in schema is missing and we call avro::encode on the data. It throws an exception, which is as expected. But the issue is with the error message. It comes the other way round.

Schema:
{code:java}
{
 "type" : "record",
 "name" : "userInfo",
 "fields" : [
    { "name" : "id", "type" : "int"},
    { "name" : "fullName", "type" : "string" }
 ]
}
{code}
The generic datum to be encoded has no "id" provided. There is an empty GenericDatum for that field. Here is the excetion that is thrown:
{code:java}
avro::Exception caught: Invalid operation. Expected: Null got Int{code}
The exception message should have been 
avro::Exception caught: Invalid operation. Expected: {color:#FF0000}*Int got Null*{color}

 

{color:#333333}Please let us know if you need more information on this.{color}
