When installing an Event Streams instance on OpenShift Container Platform 4.5.0 to 4.5.5 by using the UI, the installation stops and an error about missing values is displayed after clicking Create. The following is an example of the error:
Error "Required value" for field "spec.strimziOverrides.kafka.listenrers".
Due to a known issue, installing on OpenShift Container Platform 4.5.0 to 4.5.5 by using the UI removes configuration details and applies an incomplete definition.
Resolving the problem
When installing Event Streams on OpenShift Container Platform versions 4.5.0 to 4.5.5 by using the OpenShift UI, go to the YAML View, select a sample configuration on the right, and click Try It to load a valid sample.
Alternatively, upgrade your OpenShift Container Platform version to 4.5.6.
