Bug: spawn and spawnChild has type error when using setup() #5356
Description
XState version
XState version 5
Description
When using setup({}) together with spawnChild in vscode, TypeScript produces a type error if an id is provided in the options.
import { createMachine, spawnChild, setup, assign } from 'xstate';
const childMachine = createMachine({});
setup({}).createMachine({
entry: spawnChild(childMachine, {
id: 'child', // Type 'string' is not assignable to type 'undefined'.(2322)
}),
});
createMachine({
entry: spawnChild(childMachine, {
id: 'child', // this ok
}),
});
setup({
types: {
context: {} as { childMachineRef?: any },
},
}).createMachine({
entry: assign({
childMachineRef: ({ spawn }) => spawn(childMachine, { id: 'child' }),
// No overload matches this call.
// Overload 1 of 2, '(logic: never, ...[options]: never): ActorRefFromLogic<never>', gave the following error.
// Argument of type 'StateMachine<MachineContext, AnyEventObject, Record<string, AnyActorRef>, ProvidedActor, ParameterizedObject, ... 8 more ..., any>' is not assignable to parameter of type 'never'.
// Overload 2 of 2, '(src: StateMachine<MachineContext, AnyEventObject, Record<string, AnyActorRef>, ProvidedActor, ParameterizedObject, ... 8 more ..., any>, options?: ({ ...; } & {}) | undefined): ActorRefFromLogic<...>', gave the following error.
// Type 'string' is not assignable to type 'undefined'.(2769)
}),
});
createMachine({
entry: assign({
childMachineRef: ({ spawn }) => spawn(childMachine, { id: 'child' }), // ok
}),
});Expected result
expected no type error
Actual result
(alias) spawnChild<MachineContext, AnyEventObject, undefined, AnyEventObject, never>(src: AnyActorLogic, options?: (SpawnActionOptions<MachineContext, AnyEventObject, AnyEventObject, ProvidedActor> & {
id?: never;
}) | undefined): ActionFunction<MachineContext, AnyEventObject, AnyEventObject, undefined, never, never, never, never, never>
