Partition Watermarks are not displayed properly

[weeco]

When I took down a node in a three node cluster I wanted to see a topic's partitions. There seem to be multiple issues with properly displaying the partitions low and high watermarks. It was expected that we cannot list the low and high watermark for partition 0, but we should present it better.

API response from server:
