Schema Registry Exception
I'm getting the following exception when trying to register a schema:
[2016-06-13 11:37:14,531] INFO 172.23.147.101 - - [13/Jun/2016:11:37:14 -0400] "POST /subjects/GenericAuditRecord/versions HTTP/1.1" 500 52 7 (io.confluent.rest-utils.requests:77)
[2016-06-13 11:38:31,292] ERROR Unhandled exception resulting in internal server error response (io.confluent.rest.exceptions.GenericExceptionMapper:37)
com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token
at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@726bacc9; line: 2, column: 5] (through reference chain: io.confluent.kafka.schemaregistry.client.rest.entities.requests.RegisterSchemaRequest["schema"])
I am posting this:
{
"schema": {
"type": "record",
"name": "GenericAuditRecord",
"fields": [
{"name": "xml", "type": ["string", "null"]},
]
}
}
Any ideas as to what I am doing wrong?

I figured it out. The value of field "schem" is just a string so I needed to escape my JSON:
{
"schema":"{\"type\": \"record\",\"name\": \"GenericAuditRecord\", \"fields\": [{ \"name\": \"xml\",\"type\": [\"string\", \"null\"] }]}"
}

Hi Dave,
This looks like invalid JSON. I see an extra comma in the fields stanza.
Maybe you can try with this (below)?
{
"schema": {
"type": "record",
"name": "GenericAuditRecord",
"fields": [{
"name": "xml",
"type": ["string", "null"]
}]
}
}
