# scheduled-job-schedule-valid-cron - ESLint plugin rules

This rule requires a scheduled job's `config.schedule` string to be a valid cron expression.

## Severity

`error`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets files in your project's `src/jobs` directory. It reports a `config.schedule` whose string value isn't a valid cron expression. Interval-based schedules, such as `{ interval: 60000 }`, aren't checked.

The following code is reported by the rule:

```ts title="src/jobs/sync-products.ts"
export const config = {
  name: "sync-products",
  schedule: "not-a-cron",
}
```

Instead, use a valid cron expression:

```ts title="src/jobs/sync-products.ts"
export const config = {
  name: "sync-products",
  schedule: "0 0 * * *",
}
```

## Why it's Important

Medusa uses the `schedule` value to determine when to run the job. An invalid cron expression means the job is never scheduled correctly.

Learn more in the [Scheduled Jobs documentation](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs).

## Fixable

This rule isn't auto-fixable.
