checkProviderRuntime error: Due to constraint configuration problems the provider will be ignored.

Hi!
I'm trying to use a CustomListener to catch Events related to Assets, which basically implements AssetListener to do something when Assent events appear:

`

public class CustomListener implements AssetListener {

private final Monitor monitor;
@Provider
public CustomListener (Monitor monitor) {
    this.monitor = monitor;
}

@Override
public void created(Asset asset) {
    AssetListener.super.created(asset);
    monitor.debug("CustomListener received CREATED event");
    // DO SOMETHING
}

// ANOTHER EVENTS ...

}

`

But following error appears during gradle build:
feb 17, 2025 9:59:31 A.áM. org.glassfish.jersey.internal.inject.Providers checkProviderRuntime WARNING: A provider CustomListener registered in SERVER runtime does not implement any provider interface s applicable in the SERVER runtime. Due to constraint configuration problems the provider CustomListener will be ignored.
And I can check during execution than Listener is not working as expected during Asset creation.

Any idea?

Thanks

I'm not sure what the @Provider annotation is meant to do here and how this listener has been registered, but I'd suggest to take a look at the Event and Callbacks section of the documentation.
