It's probably a CloudWatch event rule? I think schedule triggers for lambdas are usually event rules.

There's some magic in the AWS console that creates them for you. When using Pulumi or similar tools, you have to do it yourself.

To confirm in the AWS console, you can view your lambda. My scheduled lambdas say that the trigger is "EventBridge (CloudWatch Events)".

Yes I can create it manually in the AWS console but I really need to do it through Pulumi, just couldn’t find out how I can do it when I create `EventRule` or `EventTarget`  via pulumi. Thought I could be missing something obvious that someone can point out.

<@U012UJTT55M> Is your trigger set up via Pulumi?

Yes. I use `aws.cloudwatch.EventRule` to define the schedule, and its `onEvent()` mixin to hook it up to the lambda handler function.

I believe there are other ways to achieve the same thing.

Ahh I think the `onEvent()` is what I’m missing. Thanks heaps, I’ll look into that

Ah yes. They're not well documented. I haven't ever found them on <http://pulumi.com|pulumi.com>. I think I got a hint from this Slack, then looked through the source code to figure them out.

`onEvent()` is defined in `@pulumi/aws/cloudwatch/eventRuleMixins.d.ts`, if you're using TypeScript.
