Description
Brief summary of the bug. What is it ? Where is it ?
Under some circumstances (we guess a process with no data) the process page fails after a Dashboard was created after using the link in the process overview for the first time.
Steps to reproduce:
- Deploy a process with no instances
- Go to the process overview page
- Click on the dashboard link of that process
- Refresh the process overview page
Actual result:
Loading hte page fails with a 500 error from the backend api.
The log contains this stacktracke:

Expected result:
it should work fine
Hint:
As discussed in a call we should make the process overview/kpi report evaluation null-safe in regards to the report value
