ApiException: Access token is expired / 401 error in long-running scripts

[coldenol]

There is an issue in getting a 401 error (ApiException: Access token is expired) after 9-10 hours of script working.

This is the possible place of the issue:

ringcentral-python/ringcentral/platform/auth.py

Line 120 in a61e873

return token_date > time()

My script is running for such a long intervals because of the API rate limits, and to download call recordings for a day it is running from 7 to 12 hours.

Unfortunately, I have no time to investigate the SDK and just trying to implement such a method in my RingCentralApi class that is being called before each API call:

    def _validate_token(self) -> None:
        """
        Checks if the token is about to expire within 60
        seconds. This is an additional layer of security to already
        existing token expiration checks in the RingCentral SDK.

        """
        expire_time = self.platform.auth().data().get("expire_time", 0)
        if expire_time <= time.time() + 60 or expire_time == 0:
            self.platform.refresh()

UPD:
The workaround with the _validate_token() method didn't help. This time the script failed after 2 hours of running.

SDK version: ringcentral-0.9.0-py3-none-any.whl

So far my script has been running for 60 hours with no http issues. Still watching.

This issue can be closed. The problem was solved by wrapping the http request in an infinite while loop that breaks after several failed attempts.

connection_retries = 4
while True:
    connection_retries -= 1
    try:
        response = <>
        return response
    except (ApiException, HTTPError, ConnectionResetError) as e:
        if (
            isinstance(e, ApiException)
            and e.api_response().response().status_code == 401
        ) or (isinstance(e, HTTPError) and e.response.status_code == 401):
            if connection_retries <= 0:
                raise HTTPError("Access token expired.")
            continue

So when getting 401 error it just repeats the request and it it usually successful.
