Actions have access to "the internet". So basically they can interact with things outside of Convex. While mutations and query can't.
Actions can call third party services to do things such as processing a payment with Stripe. They can be run in Convex's JavaScript environment or in Node.js. They can interact with the database indirectly by calling queries and mutations.https://docs.convex.dev/functions/actions

Ah that's tough, you didn't see the error because it was a scheduled function?
When I run a mutation that fetches directly I get
but since you scheduled this, you would have had to check the dashboard logs to see the error
