Sending notifications via action node isn't working anymore

[neilenns]

For years I've had an action node configured to send notifications to my Android device based on the incoming payload. It's configured like this:

The incoming payload is created using a function node and specifies all the necessary info to send the notification:

const newPayload = 
{
    "target": msg.payload.target,
    "data": {
        "title": msg.payload.title,
        "message": msg.payload.content,
        "data": {
            "push": {
                "thread-id": msg.payload.data.tag,
                "apns_headers":
                {
                    "apns-collapse-id": msg.payload.data.tag
                }
            },
            ...msg.payload.data
        }
    }
}

Recently I noticed I'm no longer receiving notifications, likely related to when I updated to a newer version of the websocket nodes. The error I'm getting is:

"ValidationError: "target" must be of type object"

It appears this is because of the notify.{{payload.target}}, which causes the node to show targets selection UI. If I replace it with notify.mobile_app_my_phone everything works.

What's the right way to specify a dynamic action now? I want to specify the phone to target as part of the incoming payload.

The msg.payload.target property is an input for the action node and must follow a specific format. Since you're constructing the entire input before reaching the action node, you should include this in the action as well. For example:

const newPayload = {
    action: `notify.${msg.payload.target}`,
    data: {
        title: msg.payload.title,
        message: msg.payload.content,
        data: {
            push: {
                "thread-id": msg.payload.data.tag,
                apns_headers: {
                    "apns-collapse-id": msg.payload.data.tag
                }
            },
            ...msg.payload.data
        }
    }
}

The other solution would be to ensure the payload object doesn’t include any supported input properties. You can review the list of allowed input properties here.

Thanks for the quick response. That did the trick!
