Error running self.parent.shotgun.info() or self.parent.shotgun.find() from context_change() hook

Hi All,

Just wondering if anyone has come across an error similar to the one I’m getting when I call self.parent.shotgun.info() from the context_change() hook?

[Errno 2] No such file or directory

To be fully clear I don’t really want the shotgun.info()… I’m actually trying to run a shotgun.find() but that is also failing with a similar error… but I’d tied shotgun.info as I thought it might be more “basic” for troubleshooting purposes.

I’ll keep debugging at my end… but if anyone’s encountered this before I’d love to hear from you :slight_smile:

Thanks
Tom

Are you running this from a renderfarm?
Or what kind of environment?

You are running into an issue where your CA certicates are not refreshed.

If you set the following environment variable:

SHOTGUN_API_CACERTS

and point it to this file somewhere on disk:

https://github.com/shotgunsoftware/python-api/blob/master/shotgun_api3/lib/httplib2/python3/cacerts.txt

Then it will work.
If running in an engine or from SG Desktop this should not be needed.
But farm processes do need this.

Hey @Ricardo_Musch ,

Thanks for your swift reply!

Turns out your were bang on the money! We have have a custom module for managing our environment variables that runs during the tank_init.py and that was overwriting the SHOTGUN_API_CACERTS env var to a non-existent file path. Now that I’ve updated our system for that so it picks it up in a more dynamic way (and finds a file that I’m distributing with the sgtk config itself) it’s working fine.

Thanks very much for your help!

Tom
