Hello, after upgrading the docker image from version 1.7.2 to 1.8.1 and wiping out zookeeper completely I see
{"errors":["Not found."]} when trying to access the webinterface of Flink. I can launch jobs from the cmdline and I can't spot any error in the logs (so far on level INFO). I tried adding the flink-runtime-web_2.12-1.8.1.jar as a dependency into the lib folder when building the Docker container, but this did not help either. Has anyone experienced this problem? Is my Flink config faulty or what could be the reason?
