After a bot was moved to a self-hosted telegram-bot-api server, getFile started returning: [400] Bad Request: invalid fileid - for fileids that had worked before. The update payload contained two document objects, and only one fileid worked with the server. The bot was still receiving updates via api.telegram.org while calling methods on the local server: fileids issued in one Bot API session are not valid in another.

Running two bot sessions at once (updates via api.telegram.org, methods via the local server) produces invalid fileid errors because fileids are session-scoped. Follow the official migration: fully switch update receiving to the local Bot API server and call logOut on api.telegram.org (waiting ~10 minutes for the old session to clear). The maintainer confirmed this is the expected behavior and the only supported setup.
