> JsonMappingException in DynamoDBStreamsSchema
> ---------------------------------------------
>
> Key: FLINK-11547
> URL: https://issues.apache.org/jira/browse/FLINK-11547
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kinesis
> Affects Versions: 1.8.0
> Reporter: Devin Thomson
> Priority: Major
> Attachments: full_flink_trace.txt
>
>
> If DynamoDBStreamsSchema is used as the deserializer for
> FlinkDynamoDBStreamsConsumer, an exception occurs during deserialization of a
> record. The stack trace is attached.
>
> This is a blocker for using DynamoDBStreamsSchema, but can be worked around
> by implementing a custom deserializer. The issue appears to be due to the
> usage of vanilla ObjectMapper:
>
> {code:java}
> private static final ObjectMapper MAPPER = new ObjectMapper();
> {code}
> When it should be using the appropriate mix-ins offered by the dynamodb
> stream adapter library:
> {code:java}
> private static final ObjectMapper MAPPER = new RecordObjectMapper();
> {code}
> This appears to resolve the issue, I tested by using my own deserializer
> implementation.
