CreateKmsUser:
Type: Task
Resource: arn:aws:states:::aws-sdk:ssm:startAutomationExecution.waitForTaskToken
# Note: Since we don't expect a return value from the supporting Lambda function, we'd prefer to use
# "ResultPath: null" so as to not pollute the data with an empty array. However, see this issue
# as to why we can't currently use "null" in the YAML form of state machines:
# https://github.com/aws-cloudformation/aws-cloudformation-resource-providers-stepfunctions/issues/41
# This approach would apply to all tasks where the state machine does not depend on a return value from
# a task.
