Uuid_v7_primary_key :id throws: (undefined_function) function uuid_generate_v7() while migrating

I just attempted to change all the to uuid_primary_key to uuid_v7_primary_key and now it is throwing the following error. I followed the documentation and ensured to have "uuid-ossp" in my Repo’s installed_extensions/0.

What could I be missing?
