• Wrap the env: block in a Helm conditional (e.g., {{- if .Values.pluginsManager.env }}) so it’s only rendered when env vars are defined. This prevents Helm from emitting null or an empty block when users don’t specify any env entries.

• Provide a default empty array for pluginsManager.env (e.g., env: []) in the values file instead of only a commented example. This ensures toYaml always produces a valid list and avoids rendering null.

Just to address the two low confidence comments: I decided not to do that and follow the existing conventions in the pluginManager (see resources:). If wanted, I can of course add conditionals everywhere + apply that to the whole chart.
