API Coinbase ValueError from get_buy_price()

I am working on some BTC data analysis and trying to make continuous requests to coinbase API. When running my script, it will always eventually crash on a calls to

r = client.get_spot_price()
r = client.get_buy_price()
r = client.get_sell_price()

The unusual thing is that the script will always crash at different times. Sometimes it will successfully collect data for an hour or so and then crash, other times it will crash after 5 - 10 minutes.

ERROR:

    r = client.get_spot_price()
  File "/home/g/.local/lib/python3.4/site-packages/coinbase/wallet/client.py", line 191, in get_spot_price

    raise ValueError(errmsg("Expecting value", s, err.value)) from None
ValueError: Expecting value: line 1 column 1 (char 0)

It seems to be crashing due to some json decoding?

Does anyone have any idea why this will only throw errors at certain times?

I have tried something like the following to avoid crashing due to this error:

#snap is tuple of data containing data from buy, sell , spot price
if not any(snap):                                                                                                 
    print('\n\n-----ENTRY ERROR---- Snap returned None \n\n')                                                     
    success = False                                                                                               
    return 

but it isn't doing the trick

What are some good ways to handle this error in your opinion?

Thanks, any help is much appreciated!
