Unrecognized field "SequenceNumber" (class com.amazonaws.services.lambda.runtime.events.SNSEvent$SNS), not marked as ignorable (11 known properties: "signatureVersion", "messageId", "signingCertUrl", "message", "signature", "type", "subject", "messageAttributes", "timestamp", "unsubscribeUrl", "topicArn"])

There is an issue with SNS FIFO. SequenceNumber is assigned to each published message, but property is not available in SNSEvent.SNS class.

Hi @ernad-delic,

Can you explain this issue a little more? Do you have SNS (FIFO) -> SQS (FIFO) -> Lambda?

What is your handler signature?

Thanks,

M
