running script returns error

[whateverDude]

I ran the script like this: python3.9 scripts/rhrad_offline.py --heart_rate data/AJWW3IY_hr.csv --steps data/AJWW3IY_steps.csv

and got following error:
/Library/Python/3.9/lib/python/site-packages/pandas/core/nanops.py", line 1703, in _ensure_numeric
raise TypeError(f"Could not convert {x} to numeric") from err
TypeError: Could not convert AJWW3IY to numeric

Would appreciate any help.
