I have a workflow that contains a bunch of activities. I store each activity's response in a S3 bucket. I pass the S3 key as an input to each activity. Inside the activity, I have a method that retrieve the data from S3 and perform some operation. But my last activity failed and threw error:
Caused by: com.amazonaws.AmazonServiceException: Request entity too large (Service: AmazonSimpleWorkflow; Status Code: 413; Error Code: Request entity too large; Request ID: null)

I know AWS SWF has some limits on data size, but I am only passing a S3 Key to activity. Inside activity, it will read from S3 and process the data. I am not sure why I am getting this error. If anyone knows, please help! Thanks a lot!
Your activity failed as respondActivityTaskFailed SWF API call is seen in the stack trace. So my guess is that the exception message + stack trace exceeded the maximum size allowed by SWF service.
