[SSL: CERTIFICATE_VERIFY_FAILED] error using supabase-py

[soyzamudio]

Hey guys!

So I was using supabase-py and all of a sudden I start getting this [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate error, it was fine yesterday (when I started using it) and earlier today, but out of nowhere I can't do anything with supabase-py (I can use request to make other api requests to other things), but I can't using the supabase-py create_client function.

this is the minimal code I'm testing with:

from decouple import config
from supabase import create_client, Client

# Initialize Supabase client
url = config("SUPABASE_URL")
key = config("SUPABASE_KEY")
supabase: Client = create_client(url, key)

def main():
    response = supabase.table('leagues').select('id, logo').limit(10).execute()
    print(response.data)
        
if __name__ == "__main__":
    main()

this is the error:

I had the same code working yesterday and this morning, but now it's all broken 🤔

Any help?

Thanks!

I've tried a ton of things that are "on the line", setting the ssl to work with unverified requests, installing the certs by double clicking the Install Certificates.command in the /Applications/Python \3.13/ folder, a bunch of other things 🤔

Been stuck on this for hours. Google is useless.
