Expected behavior

should have installed manifests to the cluster without errors

The error occurs because the generated YAML uses the deprecated apiextensions.k8s.io/v1beta1 for the FlyteWorkflow CRD, which is not supported in Kubernetes v1.22+; your cluster is v1.34.1. This happens if Helm's capabilities detection fails during templating, causing it to default to the old API version. To fix, run helm template with the --validate flag or ensure your Helm environment can detect the available Kubernetes API versions, so it emits apiextensions.k8s.io/v1 instead of v1beta1 for CRDs. See the template logic in flyteworkflow.yaml.

If you still see v1beta1, check for Helm caching or cluster API detection issues. This is a known issue, and the chart has been updated to use v1 by default when supported, but proper cluster API detection is required for the template to render the correct version. Would you like more detail on how to force Helm to use the correct apiVersion or how to patch the chart?
