### Question

After configuring it  withEnv("DYNAMODB_WRITE_ERROR_PROBABILITY", "1.0") — it is expected to throw dynamo throuput exception , but throwing 500 error - `(Service: DynamoDb, Status Code: 500, Request ID: null, Extended Request ID: null)","operationType":"PutItem","kinesisRecordMetaData":{"recordInsertionDate":"01-01-2021"}}, Response - PutObjectResponse(ETag="5435b0664a1337227d380fbd83ebcc89")

### Anything else?
