Custom converters : doc is broken

[ThomasKientz]

Exemple as is from documentation (https://vuefire.vuejs.org/guide/realtime-data.html#Firestore-withConverter-) throws Typescript errors :

error TS2322: Type '(snapshot: QueryDocumentSnapshot<DocumentData, DocumentData>) => (DocumentData & { readonly id: string; }) | null' is not assignable to type '(snapshot: QueryDocumentSnapshot<DocumentData, DocumentData>, options?: SnapshotOptions | undefined) => TodoI'.
  Type '(DocumentData & { readonly id: string; }) | null' is not assignable to type 'TodoI'.
    Type 'null' is not assignable to type 'TodoI'.

             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    The expected type comes from property 'fromFirestore' which is declared here on type 'FirestoreDataConverter<TodoI, DocumentData>'

error TS2322: Type '{ (modelObject: WithFieldValue<VueFirestoreDocumentData<DocumentData>>): WithFieldValue<DocumentData>; (modelObject: PartialWithFieldValue<...>, options: SetOptions): PartialWithFieldValue<...>; }' is not assignable to type '{ (modelObject: WithFieldValue<TodoI>): WithFieldValue<DocumentData>; (modelObject: PartialWithFieldValue<TodoI>, options: SetOptions): PartialWithFieldValue<...>; }'.
  Types of parameters 'modelObject' and 'modelObject' are incompatible.
    Type 'WithFieldValue<TodoI>' is not assignable to type 'WithFieldValue<VueFirestoreDocumentData<DocumentData>>'.
      Type 'TodoI' is not assignable to type 'WithFieldValue<VueFirestoreDocumentData<DocumentData>>'.
        Property 'id' is missing in type 'TodoI' but required in type '{ [x: string]: any; readonly id: string | FieldValue; }'.

    'id' is declared here.

            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    The expected type comes from property 'toFirestore' which is declared here on type 'FirestoreDataConverter<TodoI, DocumentData>'

Any idea what is missing to make it work ?
