[Beats Management] Beats List TypeError exception and white screen

[Alufolie303]

Kibana version: 7.3.0

Elasticsearch version: 7.3.0

Server OS version: Ubuntu 16.04

Browser version: Firefox 68.0.1

Browser OS version: Windows 10 17134

Original install method: apt install (official Repo)

Describe the bug:
Beats Central Management( /app/kibana#/management/beats_management) doesn't work.
After opening the Central Management Application for a short moment the enrolled beats view comes up and disappears again. After this just a white page is shown.

Steps to reproduce:
I can't test this, but I think the behaviour is related to Kibana/Elasticsearch Version 6.8.
So I've created in the past on Elastic Stack 6.8. some beats enrollment configurations. Since the update to 7.3.0 the behaviour, described above, is present.

Solution (sledgehammer approach):
Delete the .management-beats index and restart with a clean configuration
