Unknown errors

[sdenenberg]

Hello,

This may or may not be a gdax-python issue and I'm hoping someone can help me understand what is going on. I am writing a script that pulls data from gdax every few seconds, using a combination of get_product_ticker, get_account, and other calls. Every 20 minutes or so my script crashes with the following traceback:

Time elapsed: -1199.2530570030212
Traceback (most recent call last):
File "test.py", line 73, in
eth_account = auth_client.get_account("1f3aee21-bd3b-42cd-899c-51cb2a648947")
File "C:\ProgramData\Anaconda3\lib\site-packages\gdax-1.0.6-py3.6.egg\gdax\authenticated_client.py", line 27, in get_account
File "C:\ProgramData\Anaconda3\lib\site-packages\requests\models.py", line 850, in json
return complexjson.loads(self.text, **kwargs)
File "C:\ProgramData\Anaconda3\lib\json_init_.py", line 354, in loads
return _default_decoder.decode(s)
File "C:\ProgramData\Anaconda3\lib\json\decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\ProgramData\Anaconda3\lib\json\decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The line that fails is different each time, the only consistency is that it is a function of gdax-python. Any thoughts?

Thanks,

Scott

For some reason the JSON decoding is failing. This library doesn't have great error handling yet - to get an idea of what's going on, you could edit get_account() in the python-gdax file pointed out by your stacktrace C:\ProgramData\Anaconda3\lib\site-packages\gdax-1.0.6-py3.6.egg\gdax\authenticated_client.py:

def get_account(self, account_id):
        r = requests.get(self.url + '/accounts/' + account_id, auth=self.auth, timeout=self.timeout)
        r.raise_for_status()
        try:
            return r.json()
        except Error as e:
            print(e)

This is a quick and dirty test that I haven't tried to run, but this should provide a bit more info when it crashes. Usually GDAX provides an informative error message when it denies a request, so hopefully this captures it.

Alright, I'll post my findings when I get them. As I come across error conditions I'll add the error handling to the various functions I'm using, thank you for the advice.
