What does your YAML for Job submission look like? And the YAML for Session cluster, for that matter.
It is hard to tell without those. Nix, From: dominik.buen...@swisscom.com <dominik.buen...@swisscom.com> Date: Thursday, June 5, 2025 at 3:40 PM To: user@flink.apache.org <user@flink.apache.org> Subject: Kubernetes Operator Flink version null for FlinkSessionsJob Hello all, I currently have an issue when deploying FlinkSessionJob deployments with the Kubernetes operator (1.11.0) for Flink 1.20.1. After successfully starting the session cluster, I receive the following error message when submitting the FlinkSessionJob: Event[Job] | Warning | UNSUPPORTEDFLINKVERSION | Flink version null is not supported by this operator version When deploying the session cluster, I see that the correct version is applied. Also, the session cluster seems to run normal, WebUI is reachable and waiting for job submissions “Loading configuration property: $internal.flink.version, v1_20” Any idea where this error message is coming from?
