We had the same problem when trying to set this up for the first time. We discovered that the lambda function is expecting the json from CloudWatch and not the default test event. The CloudWatch json has a data field that the function decodes from base64. Replacing the test event with the json below should work.

{
  "awslogs": {
    "data": "QVdTIGxvZyBjb250ZW50"
  }
}
