TypeError: None has type NoneType, but expected one of: int, long

When I run python generate_tfrecord.py --csv_input=data/test_labels.csv --output_path=data/test.record --image_dir=images/test/ I get

  File "generate_tfrecord.py", line 104, in <module>
    tf.app.run()
  File "E:\Miniconda\lib\site-packages\tensorflow_core\python\platform\app.py", line 40, in run

    return tf.train.Feature(int64_list=tf.train.Int64List(value=value))
TypeError: None has type NoneType, but expected one of: int, long

As an output

I have change the pbtxt file and the generate_tfrecord file with my object and the id
