Kong: Error with jwt_secrets.key in kong 1.3

[mickaelmagniez]

Summary

I'm trying to update from 1.2 to 1.3 (db less), and this configuration prevent kong 1.3 to start:

_format_version: "1.1"

consumers:
  - username: foo

jwt_secrets:
  - consumer: foo
    key: "https://keycloak/auth/realms/foo"
    algorithm: RS256
    rsa_public_key: "-----BEGIN PUBLIC KEY----------END PUBLIC KEY-----"

Error is

nginx: [error] init_by_lua error: ...are/lua/5.1/kong/db/schema/others/declarative_config.lua:423: attempt to index local 'parent_fk' (a nil value)
stack traceback:

        /usr/local/share/lua/5.1/kong/init.lua:430: in function 'init'
        init_by_lua:3: in main chunk

Removing key: "https://keycloak/auth/realms/foo" fixes error, but of course jwt validation doesn't work.

Hello, same issue here.

Back to 1.2 works ok.
