Hello,
I'm a data engineer for Madup, Inc. I have a question about
GoogleAdsService API.
I've tried to download an 'ad_group_criterion' report using google ads
python library (v7).
Due to the volume of the data, it takes a couple of hours, but it always
fails with "Page token has expired" error.
Here's a response I've got:

I read the other discussions
<https://groups.google.com/g/adwords-api/c/f4fTkTo8m_o> so I tried to
download with page_size as 10000, but it fails again.
One weird thing is that the 'page token has expired' error occurs *exactly*
4 hours after the first request is sent.
>From the above discussion, page_token is valid for 2 hours, but it's not
related to this case because I processed every page in 7~10 secs and
re-requested the next page. (Furthermore, I got the error after 4 hours
from the first request, not 2 hours.)
I also tried to use 'search_stream' instead of 'search' for test on my
locals, but I got an rpc error while pulling data. I think it's because of
the unstable network. So I'm trying to test on our cloud infra. If it works
well, I'd like to use search_stream, but anyway I'm curious why I've got
that page token error.
Thanks!
