I have a python script within a docker container. I mount a folder with .session files as a volume to the container. When I connect to telegram locally, with jupyter, it works perfectly fine: When i run container in interactive mode, I can see .session file is mounted. Permissions seems to be sufficient. Env variables are correct. I checked if session file can be reached from the code in the interactive mode - yes. There is only a TELETHON_SESSION_PATH on the picture, but TELEGRAM_API_ID and TELEGRAM_API_HASH are also present and are correct. Here is my script. I used to use a context manager, but switched to plain .connect because it's easier to debug. For the same reason, I've added SQLiteSession.
