Serverless triggers are not being deployed

**Describe the Issue:**

Hi! I'm trying to use doctl to deploy a serverless function with a cron trigger. When I run the `doctl serverless deploy` command my function is deployed but the trigger is not. I do not see a section in my console output for the trigger.

**Environment:**

- doctl version: `1.101.0-release`
- OS: Ubuntu
- Installation method: Snap

**Additional Details:**

Adding a `trace` flag provides no additional output. My project file looks like this:

```yaml
packages:
- name: jobs
shared: false
functions:
- name: test
runtime: go:default
web: false
triggers:
- name: cron-trigger
sourceType: scheduler
sourceDetails:
cron: "0 12 * * *"
withBody: {}
```
