It seems to happen only with Anaconda CE image. 

Prerequisites (if any, like setup, operators/versions):

Anaconda CE enabled

Steps to Reproduce

1. Spawn ACE image from JupyterHub
2. once the image is spawned, wait 1-2 minutes

Actual results:

"Directory not found" error popup appears

Expected results:

"Directory not found" error popup does not appear

Reproducibility (Always/Intermittent/Only Once):

Intermittent

Build Details:

RHODS v1.6.0-8

Anaconda image v0.0.2

Workaround:

click on "Dismiss" button to keep working without issues

Additional info:

Something similar happens if by doing the following:

1. spawn ACE image
2. create a directory
3. move inside the directory
4. open a terminal
5. delete the directory
6. wait for the pop up error saying that directory is not found

The situation seems similar, but before getting the issue no one has deleted a directory or something like that.
