Error generating CSV from Discover screen (Failed to generate report: TypeError: Cannot read property 'settings' of undefined)

[gsmith-sas]

I have deployed ODFE 1.12.0 into my Kubernetes cluster using the Helm chart. Elasticsearch and Kibana appear to be working fine. However, when I tried to generate a CSV (via Reporting -> Generate CSV) while on the Discover screen, it fails. A message dialog appears in the lower right of the browser window with the message:

Download error
There was an error generating this report.

If I go to the Reports screen (via Reporting -> View Reports), I see an entry for the attempt (with a state value of "Created") but clicking on the CSV download link displays a message dialog indicating there was an error.

I found these messages in the Kibana log generated when I made the original request to create the CSV:
