Homer for FNIRS - Training by openfnirs Day 5 (2021)

I am a learner of Homer, I was trying the tutorials provided by the training. I have a trouble with running this code displayStats. I am getting this error message, please let us know what the issue is. I have attached the dataset and command window environment/error message (notes) in this google drive link. Also, I have pasted the error message for you to look over. It would be a great help if you guide through this, Thank you!
