PolyApiException[status_code=None, error_message=Request exception!] - 5s timeout but matched/filled. #273
Description
Have seen it a couple of times lately, from time to time i receive multiple: Request exception! without any error code.
My assumption here is: exception = retry because i did not expect this order is in the books.
But all initial and retried orders are matched without proper response.
Timelines:
17:48:14 | [Poly] ORDER REQUEST: {"token_id": "99258577478211602511334769156801132421571371614708399872000923947126441901284", "amount": 2.0, "side": "BUY", "price": 0.99, "type": "FOK"}

Expected: no orders filled/matches. Reality: 3 orders are matched:

The exception pops up somewhere in this part of the library:
def request(endpoint: str, method: str, headers=None, data=None):
try:
resp = requests.request(
method=method, url=endpoint, headers=headers, json=data if data else None
)
if resp.status_code != 200:
raise Exception(resp)
try:
return resp.json()
except requests.JSONDecodeError:
return resp.text
except requests.RequestException:
raise Exception(error_msg="Request exception!")
or here:
def request(endpoint: str, method: str, headers=None, data=None):
try:
headers = overloadHeaders(method, headers)
if isinstance(data, str):
# Pre-serialized body: send exact bytes
resp = _http_client.request(
method=method,
url=endpoint,
headers=headers,
content=data.encode("utf-8"),
)
else:
resp = _http_client.request(
method=method,
url=endpoint,
headers=headers,
json=data,
)
if resp.status_code != 200:
raise PolyApiException(resp)
try:
return resp.json()
except ValueError:
return resp.text
except httpx.RequestError:
raise PolyApiException(error_msg="Request exception!")
Looking at the datetime in the logs it is always ~5s after the request was posted, so probably a timeout setting, but i couldnt find any configuration/variable for a setting like this?!
Any suggestions on how to deal with timeouts in this situation? I could check for open orders but then it will be some fuzzy matching, which i dont like. Preferably i want to trust on the library output (exception === failure === no filled order).
Server is co-located, few hops away from poly servers and the network is really stable...
