This allows the Lambda function to receive and deserialize the original JSON object correctly.
Question
A developer deploys an Amazon SNS topic and creates a subscription for an Amazon SQS queue. An AWS Lambda function processes messages in the SQS queue. The Lambda function deserializes each message body and processes the resulting object. When the developer tests the solution, a JSON object is published to the SNS topic. However, the Lambda function returns an error when the function attempts to deserialize the message body. The error states that the message is not valid JSON. The developer must resolve the error. Which solution will meet this requirement?
