Argument of type 'void' is not assignable to parameter of type 'Action'

Question

i'am new to Typescript and using VSCode.

Getting following Error:

*[ts] Argument of type 'void' is not assignable to parameter of type 'Action'. (parameter) action: void

Code:

  loadItems() {
    return this.Apiname.find()
        .map(
        (data) => console.log("data:", data)
        )
        .map(
        payload => ({
            type: 'LOAD_ITEMS',
            payload: payload
        },
        )
        )
        .subscribe(
        action => this._store.dispatch(action)//Error
        );
};

Any help will be very helpfull.

Your map statement contains trailing ,, which could be the problem. I'd adjust the code like that:

return this.Apiname.find()
    .do( (data) => console.log("data:", data) )
    .map(
        payload => ({
            type: 'LOAD_ITEMS',
            payload: payload
        //},)
        })
    )
    .subscribe(
        action => this._store.dispatch(action) // no error
    );

now action is of type { type: string, payload: ... }
