How to get a response when using callService and calendar.list_events?

[tonka3000]

Hi,

I try to use callService to get the calendar events of an entity. I have an issue because I always get the error

{
  code: 'unknown_error',
  message: 'Service call requires responses but caller did not ask for responses'
}

The message make sense but I could not find a way to add the response variable as it is done on the service side. I either became an error from typescript or an error from the server that the key is not allowed.

How can I get response data via callService?

Here is my code snippet.

const rc = await callService(
    con,
    "calendar",
    "list_events",
    {
      duration: {
        hours: 96,
        minutes: 0,
        seconds: 0,
      },
    },
    { entity_id: "calendar.mytestcalendar" } 
  );

My Home Assistant instance is on 2023.9.2.

Thanks in advance
Michael

Did you figure this out @tonka3000 ? Running into the same issue

[tonka3000]

@shannonhochkins Sadly no. Still not sure how to do it.

I got it to work using sendMessagePromise, did you want me to show you?

[shannonhochkins]

You're not by chance using ha-component-kit are you?

Sure

No. I build https://www.raycast.com/tonka3000/homeassistant

With sendMessagePromise from the Connection object,

store.connection?.sendMessagePromise({
      type: "execute_script",
      sequence: [{
        "service": "calendar.list_events",
        "data": {
          "duration": {
            "hours": 24,
            "minutes": 0,
            "seconds": 0
          }
        },
        "target": {
          "entity_id": "calendar.ENTITY_NAME"
        },
        "response_variable": "service_result"
      },
      {
        "stop": "done",
        "response_variable": "service_result"
      }]
  })

This gave me a response correctly, however the summary html is stripped out and replaced with new line characters, if you want the html value of the event, you'll need to use the api, start/end dates as Date values

  async callApi (endpoint: string, options: RequestInit) => {
    try {
      return fetch(`${hassUrl}${endpoint}`, {
        ...options,
        headers: {
          Authorization: "Bearer " + connection?.options.auth?.accessToken,
          "Content-type": "application/json;charset=UTF-8",
        },
      }).then((response) => response.json());
    } catch (e) {
      console.error(e);
      throw new Error(
        `Error with request to Home Assistant for endpoint: "${endpoint}", please check your request params are correct.`,
      );
    }
  }
  // usage
  const params = encodeURI(
    `?start=${start.toISOString()}&end=${end.toISOString()}`
  );
  const events = await callApi<CalendarEvent[]>(`/api/calendars/${entity.entity_id}${params}`, {
        method: "GET",
      });

keep in mind you'll need to enable api: in the configuration of home assistant to use the api

I've been building something completely different, but there might be some reference there for you - the calendar card is still in development

@shannonhochkins The project looks awesome. Great work 🎉

Yeah, we building something different but share the js lib in common.

Thanks for your snippet, I will try to use it your way.
