Bug: Emit cannot infer type

[oskar-martensson]

XState version

XState version 5

Description

Type of emit cannot be inferred when when defining an action.

Example

setup({
  types: {
    emitted: {} as { type: 'apple', value: string } | { type: 'banana', value: number }
  },
  actions: {
    appleAction: emit({ type: 'apple', value: 'fruit' }),
    bananaAction: emit({ type: 'banana', value: 2 })
  },
});

Expected result

Type should be inferred.

Actual result

Type '{ type: string; value: string; }' is not assignable to type '{ type: "apple"; value: string; } | { type: "banana"; value: number; }'.
