How can I get an ARN reference generated from serverless (AWS cloudformation) within a lambda function

Serverless Framework

I have a lambda function that needs to run a DMS replication task and right now I’m doing it like this:

const AWS = require('aws-sdk');

var dms = new AWS.DMS();
var params = {
  ReplicationTaskArn: 'arn:aws:dms:us-east-1:XXXXXXXX:task:YYYYYYYY',
  StartReplicationTaskType: 'reload-target',
};

dms.startReplicationTask(params, function (err, data) {});

As you can see, I’ve hardcoded the ReplicationTaskArn, but this ARN changes because the Replication Task is generated by serverless (cloudformation). Is it possible to somehow get a reference to the replication task and then use that reference in the lambda function (instead of hard-coding the Task ARN)?

Relevant parts of the serverless.yml file:

functions:
  runDmsTask:
    handler: src/functions/runDmsTask.runDmsTask

resources:
  Resources:
    myReplicationTask:
      Type: AWS::DMS::ReplicationTask
      Properties:
        ReplicationTaskIdentifier: my-replication-task
  Outputs:
    myReplicationTaskArn:
      Value:
        Ref: myReplicationTask
