org.apache.avro.SchemaParseException: "enum" is not a defined name - avro

Question

I'm using following tool
<dependency>
<groupId>tech.allegro.schema.json2avro</groupId>
<artifactId>converter</artifactId>
<version>0.2.7</version>
</dependency>
to convert json to avro, but I'm getting exception
Caused by: org.apache.avro.SchemaParseException: "enum" is not a defined name. The type of the "enumValue" field must be a defined name or a {"type": ...} expression.
at org.apache.avro.Schema.parse(Schema.java:1265)
at org.apache.avro.Schema$Parser.parse(Schema.java:1032)
at org.apache.avro.Schema$Parser.parse(Schema.java:997)
... removed by me, our code ...
for avro schema:
{
"namespace": "test",
"type": "record",
"name": "test",
"fields": [
{
"name": "enumValue",
"type": "enum",
"symbols": [
"val_a",
"val_b"
]
}
]
}
and json:
{
"enumValue": "val_a"
}
dependency tree shows avro 1.8.2

while enum definition seems to be quite the same as the one from avro home page:
For example, playing card suits might be defined with:
{ "type": "enum",
"name": "Suit",
"symbols" : ["SPADES", "HEARTS", "DIAMONDS", "CLUBS"]
}
So what can be wrong here? Definitions seems to be OK (is it?), latest avro seems to be used and that one should support enums. So what is wrong here?

Answer 1

I was wrong, correct definition looks like:
{
"namespace": "test",
"type": "record",
"name": "test",
"fields": [
{
"name": "enumValue",
"type": {
"name": "EnumType",
"type": "enum",
"symbols": [
"val_a",
"val_b"
]
}
}
]
}
