There was a problem hiding this comment.
Have to change from CanceledErrorCode -> DeadlineExceededErrorCode but aws-sdk-go went in maintenace mode and aws-sdk-go-v2 handles error differently

Overview:
Our DAX got latent and context started getting deadline exceeded. Below is the message which we were logging in our server:
error ddb/de_entity_generic_get.go:99 couldn't get item {"id": "b1ace8e8-7f7a-4e44-af2a-4a4378ee1816", "table": "de-entity-map", "pk": "********", "sk": "********", "error": "RequestCanceled: request context canceled\ncaused by: context deadline exceeded”}Breaking down the error log:
context deadline exceeded- This is received from DAX serverRequestCanceled: request context canceled- This is generated by aws-dax-go client.We can see that the error log is misleading.
Description of changes:
