Error message "com/google/gson/internal/LinkedTreeMap" when using Kafka sink with AVRO and Schema Registry

[vszyndler]

Description

Streaming Integrator Tooling displays an error message "com/google/gson/internal/LinkedTreeMap" when trying to send events via Kafka transport in Avro format using confluent Schema Registry, as explained in the streaming Integrator documentation.

In the Event Simulator, Siddhi App Status is FAULTY.

If I try to start the App (using the Start button above), the following error message is displayed : "Error! Error while parsing Errors in Siddhi app.com/google/gson/internal/LinkedTreeMap"

Steps to Reproduce

• Start Streaming Integrator Tooling
• Create a new App and paste following code (from the streaming Integrator documentation).

@App:name("PublishKafkaInAvroFormatUsingSchemaRegistry")

@App:description('Send events via Kafka transport using Avro format')

define stream SweetProductionStream (name string, amount double);

@sink(type='kafka',
topic='kafka_result_topic',
bootstrap.servers='localhost:9092',
is.binary.message='true',
@map(type='avro',schema.registry='http://localhost:8081',schema.id='1'))
define stream LowProductionAlertStream (name string, amount double);

@info(name='EventsPassthroughQuery')
from SweetProductionStream
select *
insert into LowProductionAlertStream;

• Save the file.
