Alerts & Reports - CSV as Message Content resulting HTTP 500

[nivdann]

I am trying to understand why there is an internal server error when creating a new alert that will send a chart as CSV file to email.

Superset Config

I using helm to deploy to my EKS running AWS.
Using Firefox and geckodriver (defaults).

Alerts and Snapshots work and are sent to my email as expected. The only thing left that is not working is CSV charts.
