ExplainerHub fails to add dashboard via add_dashboard endpoint

[gamis]

Hi! Great library you have here, really enjoying it.

I'm trying to set up ExplainerHub with the add_dashboard_route, and it's not working. "ERROR: Failed to add dashboard!". If I print the traceback leading to that error, I get the trace below.

Any ideas?

Details

import explainerdashboard
db1 = explainerdashboard.ExplainerDashboard.from_config('ll_fce10_proc_20200227_100455_l1.yaml')
explainerdashboard.ExplainerHub([db1], add_dashboard_route=True).run(debug=False)

Starts up fine, I can load db1 fine, but when I got to add a second db via http://127.0.0.1:8050/add_dashboard/ll_fce10_proc_20200117_105803_l1.yaml, I get
