More Than 20 Scheduled Jobs ?

For example this config:

{
  "jobs": [
    {
      "functionLocation": "/my-file.js",
      "functionName": "myFunc",
      "executionConfig": {
        "cronExpression": "0 1,2,3 * * *"
      }
    }
  ]
}

it will run the function myFunc() inside backend/my-file.js file three times
At 01:00 AM, 02:00 AM and 03:00 AM

Note: You can schedule your job to run at intervals as short as one hour apart, but not shorter. If you define your job to run more frequently, the job will be ignored.
