@lucferbux, thank you for your PR. To double-check something, we are temporarily hardcoding the OPenAPI spec.

I'm assuming that as soon as the BFF has the Stub API implementations, we will automatically generate this file. Is that correct?

Yes, that's right. The idea would be auto generate it once the backend is set up.
