Link unfurling fails because of missing conversationType

[jdite]

I implemented the link unfurling example code in my project.
This works for unfurling links pasted in chats, but when I call the sharing feature from @microsoft/teams-js it breaks.

sharing.shareWebContent({
    content: [{
        url: sharingUrl,
        type: 'URL',
        message: `Take a look at this item`,
        preview: true,
    }]
});

This should show a unfurled preview like so:

But that doesn't work because in the request payload sent to the bot the Conversation.ConversationType is missing.
But in a chat the ConversationType is "groupChat" and it works.

JSON deserialization for type 'Microsoft.Teams.Api.Conversation' was missing required properties including: 'conversationType'.

Can you please share the entire activity payload (w/ PII redaced ofcourse)?

This is the payload sent from teams when i paste the link in a chat:

And this is the payload when i try to share the link with a preview:

Notably this is without a conversationType
