Summary: Flink UI shows server error on selecting back pressure on a batch job
Key: FLINK-16872
URL:
https://issues.apache.org/jira/browse/FLINK-16872 Project: Flink
Issue Type: Bug
Affects Versions: 1.10.0
Environment: flink 1.10
Reporter: Nikola
Attachments: Screenshot 2020-03-30 at 19.58.04.png
I have a batch job which when I click on "Back pressure" it shows a bubble saying "Server error". The reason is because the backend returns 500 error.
