JSONDecodeError: Invalid \uXXXX escape

[Tom-Gorup]

I keep getting a JSONDecodeError: Invalid \uXXXX escape at step 7 of 8. I made some adjustments to the load_data function in helper.py in an attempt to isolate the problem:

def load_data(_log_file):
    """
    Load each data set as json file
    """
    # Load the data
    with open(_log_file) as _file:
        try:
            print(_file)
            return_set = json.load(_file)
            return return_set
        except Exception as e:
            print(_file)
            print(e)

It appears the tool is struggling with the browsing_365mashbir.json file. Any idea's on how to resolve this? I've attempted to look at character 9,502,718, but uncertain as to what I should expect to see vs what's there.

<_io.TextIOWrapper name='Data/Legitimate/browsing_365mashbir.json' mode='r' encoding='UTF-8'>

Appreciate the assist!
