Cannot download file from browser

Hi, we ran into such an issue that when using this hdfscm to connect to a remote hdfs, right-click on a file in the left bar and click "download" doesn't work. The error message from the Jupyter server is below:

Error message from jupyter server:

    TypeError: initialize() missing 1 required positional argument: 'path' 

According to jupyter-server/jupyter_server#1313, a path field needs to be set in the file_handler_params.

The versions we are using are:

• Jupyter Server: 2.5.0
• hdfscm: 0.1.1

Thank you!
