Dashboard error: error handling message Message 'EVENT' (revision 1) content

[mattiasmar]

Issue: Error when 'selecting directory' inside dashboard.

Error message: error handling message Message 'EVENT' (revision 1) content: '{"event_name":"button_click","event_values":{"model_id":"1058"}}': KeyError('Wall-Clock Time',)

Steps to reproduce.

1. Build the dockerfile of the gitrepo using the command 'make build' in docker directory.
2. Add firefox to the docker image (apt-get install -y firefox)
3. Execute dashboard (command: dashboard) inside the docker.
4. Select a directory created by a coach agent.

Note: Instructions on how to visualize the firefox GUI running inside the docker on the local host are available here: docker GUI
