Problem:
- given:
- I go to the report builder
- when:
- I select any report with group by "flow node"
- then:
- the report builder freezes
- expected:
- the report builder shows the report
Hint:
It seems that we're using findFirst() on the stream api although it says NullPointerException - if the element selected is null and we assume that selecting data for not defined tenants has the entry null.
