Missing Signing Key. JWT authentication will not work

System Ubuntu 18.04.4 LTS

Security Config.yml Section

    jwt_auth_domain:
            description: "Authenticate via Json Web Token"
            #enabled: true
            http_enabled: true
            transport_enabled: true
            order: 0
            http_authenticator:
              type: jwt
              challenge: false
              config:
                signing_key: |-
                        -----BEGIN PUBLIC KEY-----

                        -----END PUBLIC KEY-----
                jwt_header: "Authorization"

                subject_key: "sub"
            authentication_backend:
              type: noop

When I try to authenticate, like this:
curl -k https://127.0.0.1:9200/content/ -H 'Authorization: Bearer eyJ0eAAAAAA.AAAAAAAA.AAAAAA'

my logs show

I am using this command to update the configs

./securityadmin.sh -cd ../securityconfig/ -icl -nhnv  -cacert /etc/elasticsearch/root-ca.pem -cert /etc/elasticsearch/kirk.pem -key /etc/elasticsearch/kirk-key.pem

It completed with Done with success.
I am sure that I am doing something wrong, but I’m not too sure what

Issue closed.
