`actions:` must be an array

[johnnydecimal]

When defining actions on a transition, if a single inline action is defined – as per the example in the XState documentation – the type definitions cause an error. Wrapping the action in an array works as expected.

// Fails
on: {
  actions: (context, event) => console.log('Fails!');
}

// Works
on: {
  actions: [
    (context, event) => console.log('Works!');
  ]
}
