Trying to dispatch an Observable

export const fetchMetaDataLogic: Logic = createLogic({
    type: fetchMetaData,
    process: ({ getState, action }, dispatch, done) => {
        const code: string = action.payload;
        const ob$ = new Observable(obs => {
            Promise.all([
                apiService.get(code)
                    .then((resp: AxiosResponse) => resp.data),
                apiService.getMeta()
                    .then((resp: AxiosResponse) => resp.data)
            ]).then(values => obs.complete()); // values dispatched
        });
        dispatch(ob$);
        done();
    }
});

Getting the Following Error.

Argument of type 'Observable<unknown>' is not assignable to parameter of type 'ArgumentAction<string, undefined, undefined>'.
  Type 'Observable<unknown>' is not assignable to type 'ActionBasis<string> & Partial<ActionBasis<string> & { payload: object; } & { meta: object; } & { error?: false | undefined; }>'.
    Property 'type' is missing in type 'Observable<unknown>' but required in type 'ActionBasis<string>'.  TS2345
