Apollo client having trouble tallking to flask backend becuase of OPTIONS request

Hello, I’m trying to integrate multiple components but I think this is ultimately an apollo question so I’m asking here. I have a gatsby frontend with an apollo client and I’m trying to send a graphql query to my backend which is a flask container with ariadne. I’m getting a network error when I try to query and I’ve narrowed it down to apollo making an OPTIONS request which fails becuase flask doesn’t support CORS by default. I added flask-cors and the request goes through if I curl it but still fails with apollo. I tried to look at the packet with tcpdump to look for differences but I’m already out of my comfort zone.

TL;DR
Apollo CORS OPTIONS request breaking when trying to talk to flask even with flask-cors installed

It turns out the issue was just me being dumb. I had an extra / at the end of the url I was trying to connect to. My bad
