I discussed the subject a little with @sampaiodiego and it seems to be a problem with DM permalink's structure, specifically the lack of a proper room name e.g:

• Group: https://open.rocket.chat/channel/general?msg=gxsHQx2cYfQjboWRF
• Direct message: https://open.rocket.chat/direct?msg=QdqwXuafvjn8aQ4sc

The "direct" token is in place of the room name for DM permalinks, which makes the link invalid. We probably need to change this if we want to change the 404 behavior / response.
