python - valueError: invalid literal for int with base 16 b ' '

Question

I am writing a script that streams from a finance API. The script streams in data points as instances of 'bytes' class, and later (not shown) outputs them to a pandas dataframe. The stream works just fine for a while, and with shorter runtimes. During longer runtimes, at some point into the stream (exactly when varies, but usually an hr or two), I get this error:

valueError invalid literal for int with base 16 b''

The full error message is included below:

error_full_traceback

A 'normal' data point is shown here:

normal 'bytes' data point

The request code connection I am using is very simple, here:

def get_stream(url=STREAM_API, token=ACCESS_TOKEN, path=STREAM_PATH, instruments=INSTRUMENTS, headers=headers):
    '''takes in neccesary parameters and outputs the input stream connection.'''
    response = requests.get("https://"+url+path+instruments, headers=headers, stream=True)
    return response

It seems like the base problem is that the request itself, during streaming, is encountering a b''{datapoint} item instead of the intended b'{datapoint} item. How can I fix this error? Am I correct in my understanding of the error?
