What directory did you launch jupyterlab in, and what is the path you are trying to open? The paths for this dialog are rooted at the directory in which you launched jupyterlab.

I open with in home, and I want to open directory in a place using absolute path like,
/media/user/data/file.py

I check the ownership of the path, and it is already owned by user.
In case of opening files in home directory, it works.

So, that feature (open from path) is only working on the current rooted directory where jupyterlab is opened?

Right. A security decision for the notebook server is that it will only serve files below the directory it was started in.

(note that symbolic links work - if you make a symbolic link from that file into somewhere below where the server started, it should work)

Closing as answered - feel free to ask more questions if you need, though.
