Hello @Mikolaj_Mularski, @FitnessBoost thank you for raising this in the community.
We are experiencing issues with the “Facebook Leads Ads - New Lead” module, which throws “Unsupported get request” errors.
Our dev team is investigating the issue. However, it seems to be caused by Meta, as users across various platforms are reporting the same issue in their community.
We’re sorry for any disruptions this is causing and we will make sure to keep you updated as soon as we learn anything new about the situation.
Thank you for your understanding.
