Calendar entity returns undefined

[pdhruv93]

The listEvents is returning undefined. I can however see events on my calendar under HA

const { api } = useEntity('calendar.work_meetings');
  return <button onClick={() => {
    api.listEvents();
}}

Can you please provide calendar settings in home assistant?

Have you tried the same service in home assistant directly?

Have you checked the documentation on the list events to see if it takes any additional required parameters?

I will take a look in the morning but more context would be helpful please

Media player had the same issue with the join service, says it expects a string but it accepts an array of strings for group_members

Also, if you come up with something nice for a calendar, send it over it may save me some time when I get to building a card for it :)

@shannonhochkins can you please provide the correct format for the start and end date, it's expecting an object.

.listEvents({
    start_date_time: {time: "2023-09-20"},
    end_date_time: {"2023-09-22T13:48:23.498075+00:00"},
  });

As mentioned above, if something doesn't work the way you're expecting it to, it's because the schema for the services provided by home assistant is wrong.

// Lists events on a calendar within a time range.
      listEvents: ServiceFunction<
        T,
        {
          // Returns active events after this time (exclusive). When not set, defaults to now. @example 2022-03-22 20:00:00
          start_date_time?: object;
          // Returns active events before this time (exclusive). Cannot be used with 'duration'. @example 2022-03-22 22:00:00
          end_date_time?: object;
          // Returns active events from start_date_time until the specified duration.
          duration?: object;
        }
      >;
      ```
      
      As you said, it's expecting an object for start/end time, but if you have a look at the description there, it's clear that it shouldnt be an object, it should be a string, have you tried as a string?

const getDatePlus20Days = (): string => {
  const currentDate = new Date();
  currentDate.setDate(currentDate.getDate() + 20);
  return currentDate.toISOString();
};

const datePlus20Days = getDatePlus20Days();
.listEvents({
    // @ts-expect-error - this is correct, types are wrong from home assistant
    end_date_time: datePlus20Days,
  });

You may need to play around with the ormatting of the date string to match the description if iso format doesn't work
