JIRA field with name Flagged does not exist

[abangerl]

Hi,

I get the config error mentioned in the title. I don't use this field name in my config and it doesn't seem to be available via the JIRA API. Is the tool somehow dependent on a special JIRA configuration or version?

My minimalistic config file (without query and credentials):

Workflow:
Backlog:
- Open
QA:
- Done
Done:
- Tested

Output:
Throughput chart: throughput.png

I am not sure if I am doing something wrong or if it is a bug. It would be great if somebody could help me out. Thank you!
