Unable to verify the AVRO schema is compatible with KSQL. Unexpected character ('<' (code 60))

[cowellrj]

Kafka 1.1

Topic being populated with JDBC Connect, serialized with Avro. Can sink the topic to another database with no issue.

ksql> CREATE STREAM users2stream WITH(KAFKA_TOPIC='JDBCTESTNEXTUSERS2', VALUE_FORMAT='AVRO'); Unable to verify the AVRO schema is compatible with KSQL. Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: (sun.net.www.protocol.http.HttpURLConnection$HttpInputStream); line: 1, column: 2]; error code: 50005

ksql-server appears to have the correct url for the schema registry (nn is my obfuscation)

ksql> show properties;

Property	Value
ksql.schema.registry.url	http://1nn.nn.nn.nn:8081

Schema registry is running and I can connect through REST API to retrieve the schema

{
'type':'record', 'name':'USERS2', 'fields':[
{
'name':'ID', 'type':{
'type':'int', 'connect.type':'int16' } }, {
'name':'USERNAME', 'type':[
'null', 'string' ], 'default':None }, {
'name':'PASSWORD', 'type':[
'null', 'string' ], 'default':None }, {
'name':'MODIFIED', 'type':{
'type':'long', 'connect.version':1, 'connect.name':'org.apache.kafka.connect.data.Timestamp', 'logicalType':'timestamp-millis' } } ], 'connect.name':'USERS2' }
