Issue when dealing with saveCall

[w-mazed]

Hi,

I need to resolve my PluginCall from another function, so I saved it through Bridge, and resolve it later, but I've message this message :

Attempt to invoke virtual method 'void com.getcapacitor.PluginCall.resolve(com.getcapacitor.JSObject)' on a null object reference

So this is a bit of my code, can you tell me guys where I'm wrong :

@CapacitorPlugin(name = "ChainwayR6")
public class ChainwayR6Plugin extends Plugin {

    Bridge bridge;
    String callbackId;
    PluginCall savedCall;

    @PluginMethod
    public void connect(PluginCall call) throws JSONException {
        String address = call.getString("address");

        implementation.connect(address);

        callbackId = call.getCallbackId();

        bridge.saveCall(call);

        // call.resolve(response);
    }


    @Subscribe
    public void onMessageEvent(MessageEvent event) {

        ChainwayR6Device deviceReader = event.getDeviceReader();

        JSObject response = new JSObject();

        JSObject props = new JSObject();
        props.put("success", event.getSuccess());

        response.put("response", props);

        savedCall = bridge.getSavedCall(callbackId);
        savedCall.resolve(response);

        bridge.releaseCall(callbackId);
        callbackId = null;
    }

Thanks.

There's no guarantee that getSavedCall will return a non-null PluginCall so you should make sure it's not-null before using it.

Take a look at how the Geolocation plugin saves calls and reuses them:
