clipboard.write(...) throws internal error (500) in personal tab

[thierschi]

I want to copy text to a user's clipboard. In the past I implemented this using the clipboard-api from teams-js. Recently this stopped working.

I tried the function in a simple button to eliminate errors on my side and made a simple button for testing:

<Button
    onClick={async () => {
        try {
            if (clipboard.isSupported()) {
                const blob = new Blob(["Hello"], {
                    type: "text/plain",
                });
                await clipboard.write(blob);
            }
        } catch (e) {
            console.error(e);
        }
    }}
>
    Test
</Button>

When trying to run this, clipboard.write(...) throws the following error:

{
    "errorCode": 500,
    "message": "An internal error occurred"
}

I've tested this in the Teams v2 Mac-App and on the web in Chrome, both show the same behaviour. In Chrome I also made sure that the teams website has access to my clipboard. Debugging into the clipboard.write() function didn't give me any hints. Maybe an issue on the receiving side of the message mechanism.
