now that the following PR is merged, I believe we can update the workflows to make sure there is a namespace when setting up the cluster

• Add option to read env variable for default namespace on activation #13

I believe @t1m0thyj may have some recommendations here

Adding this step to the workflow in between "Start K3s Cluster" and "Create System Test Properties" should fix it (source):

            - name: Set K8s Namespace
              if: ${{ always() && steps.k3s.outcome == 'success' }}
              run: kubectl config set-context --current --namespace=default
