'Name or Service not known' when running

[kaltec-w]

Hello,

I just cloned the repo and am following the directions to run the tool to collect the AH data. I successfully created a dev account and am using the following command to run (in a VENV):

BN_CLIENT_ID="<omitted>" BN_CLIENT_SECRET="<omitted>" python -m ah.updater --game_version classic us

Here's the error message I get:

It looks like it's trying to connect to 'regionenum.us.api.blizzard.com', which is not a valid host. Any suggestions on resolving this issue?

Thank you for the report,

It seems to be a serialization issue when str(RegionEnum.US) gives regionenum.us.

You can find the definition of RegionEnum here:
https://github.com/kamoo1/TSM-Backend/blob/2638bb5439670d93d1adc262a7659f87992a26ff/ah/models/blizzard.py#L57

I haven't run into this myself, though it doesn't seem likely, python version could be a factor. Could give python3.10 a try? If that fixed the problem you have, please let me know, thanks!

That was indeed the cause, I'll look for a solution.

Hey @kaltec-w, I have pushed the fix in e20b58d (dev)
