Conway [12.0.0-alpha.4] - New certificates .kind() return in correct value.

[Ryun1]

Using Conway Alpha Build: @emurgo/cardano-serialization-lib-nodejs@12.0.0-alpha.4.

Describe the bug

• When using the .kind() call on new Conway certificates I get incorrect indexes, when comparing to the Conway CDDL schema.
• Using .kind() on older certificates the correct value is returned.
• Perhaps I misunderstand what .kind() is meant to do?

Expected behaviour

Old Certificates (working):

• console.log(CSL.Certificate.new_stake_registration(CSL.StakeRegistration.new(randomCredential)).kind());
  • 0 is expected and 0 is returned.
• console.log(CSL.Certificate.new_stake_deregistration(CSL.StakeDeregistration.new(randomCredential)).kind());
  • 1 is expected and 1 is returned.
• console.log(CSL.Certificate.new_stake_delegation(CSL.StakeDelegation.new(randomCredential, randomKeyHash)).kind());
  • 2 is expected and 2 is returned.

New Certificates (not working):

• console.log(CSL.Certificate.new_vote_delegation(CSL.VoteDelegation.new(randomCredential, randomDRep)).kind());
  • 9 is expected (see CDDL), but 15 is returned.
  • console.log(CSL.Certificate.new_drep_registration(dRepRegCert).kind());
  • 16 is expected (see CDDL), but 10 is returned.
  • console.log(CSL.Certificate.new_drep_deregistration(dRepDeRegCert).kind());
  • 17 is expected (see CDDL), but 9 is returned.

(sorry I did not have time to test every new cert🙏)

It is not cbor map key. It is number of our internal enum. See CertificateKind enum to match types from kind() function. Also as there is possibility to serialize StakeRegistration and StakeDeregistration with coin and without coin these types have two constructors new and new_with_coin depends on it these types serialize into different certs according to CDDL.

Understood - thank you @lisicky 🙏

If you wanna to check a cbor map key of certificate you can serialize a certificate into cbor in look into cbor by third party tool. Like https://cardananium.github.io/cquisitor/ (made by me) or https://cbor.nemo157.com
