We're hosting Odoo 15.0 Enterprise Edition on Odoo.sh.

I've developed several custom integrations between Odoo and the other platforms our company uses. My most recent integration requires another platform to connect to our Odoo instance, and I'm unable to get API keys working in either a staging branch or production branch. I can log in from the "odoorpc" module in Python no problem with my password, but the API keys I've generated for either branch do not work and raise "odoorpc.error.RPCError: Access Denied".

Anyone have any ideas?
