Serverless Framework - unrecognized property 'params'

I am trying to create a scheduled lambda function using the Serverless framework and to send it different parameters from different events.

here is my serverless configuration:

functions:
  profile:
    timeout: 10
    handler: profile.profile
    events:
      - schedule:
          rate: rate(1 minute)
          params:
            hello: world

The issue is that when I run sls deploy, I get the following error:

Serverless:   at 'functions.profile.events[0]': unrecognized property 'params'

This is basically copied from the documentation here, so should work...

Am I missing something?

The documentation you're referencing is for Apache Open Whisk.

If you're using AWS, you'll need to use input as shown in the aws documentation

functions:
  aggregate:
    handler: statistics.handler
    events:
      - schedule:
          rate: rate(10 minutes)
          enabled: false
          input:
            key1: value1
            key2: value2
            stageParams:
              stage: dev
