When I run command python3 erpnext_sync.py its showing below error.

Traceback (most recent call last):

with open("/path/to/file_name.json", 'ar+') as f:
        param_json = json.load(f)

The mode 'ar+' is not valid in Python 3. In Python 3, valid modes for the open() function include:

'r': read
'w': write (overwriting the file)
'a': append
'b': binary mode
'+': update (read/write)

with open("/path/to/file_name.json", 'a+') as f:
        param_json = json.load(f)
