EmrStepSensor Failed due to Security ToKEN Expiration

Hi Guys,

We use EmrStepSensor to check our EMR step completion and since our running time increased over 1 hour which led to EMR step sensor failure with the Error

botocore.exceptions.ClientError: An error occurred (ExpiredTokenException) when calling the DescribeStep operation: The security token included in the request is expired

Any suggestions on how to refresh or regenerate the security token to keep the EmrStepSensor active after 1 hour expiration?
