Since 1 or 2 weeks I start to have a CORS / 400 Error on a specific route which is:
It happens only in dev / staging env (both same API KEYS) where it doesn’t happen in my production env.
I tried a lot of stuff: generating new API KEYS, removing all staging experiments, updating SDK versions, changing pc, network but nothing seems to change that, it seems to be related to the staging project/deployment on Amplitude Experiment.
It’s really annoying for my devs and me as it’s spamming constantly the console and as a dev, having errors in the console is just frustrating.
If you have any clue on that subject, please help me, thanks! :)
