Object detection using hailo8 and yolo26

I want to use yolo26 for object detection task on rpi5 but can don’t receive found objects. I upgraded previous hailo-apps to latest version

Running detection sample results in error below

cd hailo-apps
source source setup_env.sh
python hailo_apps/python/pipeline_apps/detection/detection.py --hef-path yolo26n

INFO | common.core | All required environment variables loaded successfully.
INFO | common.core | Found HEF in resources: /usr/local/hailo/resources/models/hailo8/yolo26n.hef

NMS score threshold is set, but there is no NMS output in this model.
CHECK_SUCCESS failed with status=6
(GStreamer): CRITICAL: gst_vec_deque_push_tail: assertion ‘array != NULL’ failed


I removed nms-score-threshold and nms-iou-threshold and was able to run pipeline but no objects were returned in callback

What parameters should I pass to yolo26 network to get the objects?
