AWS lambda serverless `schedule` event creation error: LimitExceededException

Question

I'm getting the following error while trying to sls deploy a function with a schedule event:

An error occurred: SupWorldEventsRuleSchedule1 - The requested 
resource exceeds the maximum number allowed. (Service: 
AmazonCloudWatchEvents; Status Code: 400; Error Code: 
LimitExceededException; Request ID: f39cee40-a651-11e8-a111-97a9e3d0f938).

Config:

functions:
  supWorld:
    handler: dist/handlers/index.helloWorld
    events:
      - schedule:
          rate: cron(*/10 * * * ? *)
          enabled: true

The strange aspect of this error is that there are no other schedule events associated with this lambda stack.

How many Cloudwatch rules are there already in your account? By default you can only have 100: https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/cloudwatch_limits_cwe.html

If I had to guess the error is occurring because you have reached the limit on your account
