Hi @murusolai … you haven’t implemented a number of changes we suggested:
You’re still making a blocking call to S3 in the message event handler. You’re saying that HandleMessageEvent is not getting called at all? But you also say that 2 of 3 queues get emptied? Please provide API documentation for AmazonS3Utility and UploadFileAsync . I can’t find it publicly. Please add some logging to the HandleFlowEvent callback as well, rather than just silently ignore. Please show us your console output at least. More importantly: please set your API logging to DEBUG and provide a full dump of API logs. See: Configuring Logging
