Review note

Might want to be sure that this is the only response where this is needed? It looks like most invoice response structs have optional description, but not all:

• CreateinvoiceResponse
• SendinvoiceResponse

I don't think these have a possible BOLT12 path but not sure.

Also this is API breaking-I don't know how versioning is handled in the crate.

Looks like the grpc mapping needs an analogous change.

These are auto-generated files you edited. The correct fix would be to fix the json schemas. I gave both waitinvoice and waitanyinvoice a quick look and they both require a description in the response. This was fine for bolt11 since invoice required a description. offer does not require a description so waitinvoice and waitanyinvoice schemas should remove description from it's required section.

Ok, thanks, closing.
