<!-- Answer -->
The issue might be related to the dynamic imports (lazy-loading) of your
custom chart plugin components. When deploying on a Kubernetes cluster, the
environment might not be correctly resolving these dynamic imports, which can
cause the plugin not to appear on the UI.
In the `ChartPlugin` class, the `sanitizeLoader` function is used to handle
dynamic imports. Ensure that your Kubernetes environment has the necessary
configurations to support these dynamic imports.
Here is a snippet from the `ChartPlugin` class that deals with dynamic
imports:
```ts
function sanitizeLoader<T extends object>(
loader: PromiseOrValueLoader<ValueOrModuleWithValue<T>>,
): PromiseOrValueLoader<T> {
return () => {
const loaded = loader();
return loaded instanceof Promise
? (loaded.then(
module => ('default' in module && module.default) || module,
) as Promise<T>)
: (loaded as T);
};
}
```
Make sure that your Kubernetes deployment is set up to handle these dynamic
imports correctly. This might involve ensuring that the necessary files are
available and correctly referenced in your deployment configuration
<sup>[[1]](https://github.com/apache/superset/blob/master/superset-frontend/packages/superset-ui-core/src/chart/models/ChartPlugin.ts)</sup>.
Additionally, you need to enable the `DYNAMIC_PLUGINS` feature flag in the
`superset_config.py` file. This can be done by specifying key/value entries in
`configOverrides` in your `values.yaml` file:
```yaml
configOverrides:
my_override: |
FEATURE_FLAGS = {
"DYNAMIC_PLUGINS": True
}
```
This configuration will ensure that the `DYNAMIC_PLUGINS` feature is
enabled, allowing you to deploy custom chart plugins in Apache Superset
