Looks like the upload to the servers works ok, but over at https://github.com/mautrix/meta/blob/9ab9bb08a402653f3880a72aff14311e65bb4699/msgconv/from-matrix.go#L78C2-L78C54 the FB ID isn't pulled out of the JSON response. In this case it seems like it should have been able to get 412640354853594 assuming that's the right ID
