Clarifai gRPC Java client throwing RuntimeException: An error occurred while executing doInBackground()

Question

I am building an Android app to predict objects in an image. I am using the Clarifai gRPC Java client for the purpose. However, I am getting a RuntimeException: An error occurred while executing doInBackground().

My code:

public class ClarifaiTask extends AsyncTask<File, Integer, Boolean> {

    protected Boolean doInBackground(File... images) {
        Security.insertProviderAt(Conscrypt.newProvider(), 1);

        V2Grpc.V2BlockingStub stub = V2Grpc.newBlockingStub(ClarifaiChannel.INSTANCE.getGrpcChannel()).withCallCredentials(new ClarifaiCallCredentials(API_KEY));

        MultiOutputResponse response = stub.postModelOutputs(PostModelOutputsRequest.newBuilder().setModelId(MODEL_ID).addInputs(Input.newBuilder().setData(Data.newBuilder().setImage(Image.newBuilder().setUrl(IMG_URL)))).build());

        if (response.getStatus().getCode() != StatusCode.SUCCESS) {
            throw new RuntimeException("Request failed, status: " + response.getStatus());
        }

        for (Concept c : response.getOutputs(0).getData().getConceptsList()) {
            System.out.println(String.format("%12s: %,.2f", c.getName(), c.getValue()));
        }

        return true;
    }
    protected void onPostExecute(Boolean result) {
        
    }
}

My error:

Any help would be appreciated.
