"messages.move() requires to specify a MailFolderId instead of a full MailFolder object."

[LispEngineer]

Hi again!

In the most recent version (6), on Thunderbird 137.0.1, when I move messages I sometimes get this on the Thunderbird error log:

Error: Support deprecated since Thunderbird 121 and removed in Manifest V3: messages.move() requires to specify a MailFolderId instead of a full MailFolder object.

It specifies the location at background.js:53.

await browser.messages.move(messageIds, folder);

I am not remotely an expert in Thunderbird, but this might work:

await browser.messages.move(messageIds, folder.id);

Per the documentation here.

Thanks!
