The issue is that the CircleCI configuration only installs the kubedb catalog for PostgreSQL as seen in https://github.com/halkyonio/operator/blob/62d85c7f64d634a1354751c919fe49c111610223/.circleci/config.yml#L93. This results in a kubedb plugin initialization failure. Should be fixed when halkyonio/plugins#3 is fixed. Alternatively, a quick fix would be to install the catalogs for mysql and mongodb, though that wouldn't address the underlying issue that a plugin should still be usable even if some combination of its provided capabilities is not available.
