I have a dashboard embedded in an iframe. I'm trying to add filters to it like so:
let my_iframe = document.querySelector("#root > main > iframe")
const eventPayload = JSON.stringify({
type: "dashboard:filters:update",
dashboard_filters: {
"Location": "now"
}
}
)
my_iframe.contentWindow.postMessage(eventPayload, location.origin)
But that doesn't work - it just returns undefined and I don't see any changes in the dashboard or any new events in the Network tab in chrome.
What am I doing wrong?
