Organization prefill parameter not working in new activity modal

[jdockwar]

When trying to create an activity, i.e. opening the new activity modal from my custom modal, then the organization parameter does nothing.

It is type checked though, in the console I get the following error, when I try to pass it as string:

Passing the deal ID works fine, and connects all the deals connected entities just fine. But in my situation I don't necessarily have a deal.

const { status, id } = await (await sdk).execute('open_modal', {
    type: 'activity',
    prefill: { 
        organization: 123, // org does nothing :(
        deal: 456 // why is deal required? This connects all entites, but even if deal is not passed, organization does not work
    },
});
