push notification to topic throws

[boscoseries]

from the documentation here https://github.com/jazzband/django-push-notifications

from push_notifications.gcm import send_message

# First param is "None" because no Registration_id is needed, the message will be sent to all devices subscribed to the topic.
send_message(None, {"body": "Hello members of my_topic!"}, to="/topics/<my_topic>_here")

when I do as stated above, I get this error

send_message(None, {"body": "Hello members of my_topic!"},
TypeError: send_message() missing 1 required positional argument: 'cloud_type'

I look up the send_message function in site-packages, it is defined like this
def send_message(registration_ids, data, cloud_type, application_id=None, **kwargs)

then I modify my arguments to send_message to contain my cloud_type and application_id thus:

    send_message(None, {"body": "Hello members of my_topic!"}, cloud_type='FCM',
                 to="/topics/<my_topic_here>", application_id="my application id")

I then get this error

here is my settings:

PUSH_NOTIFICATIONS_SETTINGS = {
    "CONFIG": "push_notifications.conf.AppConfig",
    "APPLICATIONS": {
        "<my application_id>": {
            "PLATFORM": "FCM",
            "API_KEY": <my api key>,
        },
    }
}

I encountered this issue. You have to fill out the application_id column in the push_notifications_gcm table in your database.

[boscoseries]

I did that. Did yours get solved with it?

[pydlv]

Yes, it solved it for me. But I am sending only to a single user and not an entire topic.

Yes, it solved it for me. But I am sending only to a single user and not an entire topic.

I can send to a single and multiple devices via the device.send_message method and it works. It is only when I try to send to users subscribed to my topics (see the directive in the screenshot) that I get that error.
