[keycloak-user] kcadm - adding a protocol-mapper

[Jamie McDowell]

Hi,

I am trying to add a client protocol-mapper however when i try and run this i get a HTTP error - 500 Internal Server Error
opt/jboss/keycloak/bin/kcadm.sh create \clients/<id>/protocol-mappers/models \-r demorealm \-s protocol=openid-connect \-s protocolMapper=oidc-usermodel-realm-mapper \-s consentRequired=false \-s config.claim.name=group_membership \-s config.jsonType.label=String \-s config.id.token.claim=true \-s config.access.token.claim=true \-s config.userinfo.token.claim=true \-s config.multivalued=true \-s name=Realm \
I can confirm that kcadm works as i have been able to create groups, LDAP mappers, realms etc...
In the server.log i can see the below error when i run the above
ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-109) Uncaught server error: com.fasterxml.jackson.databind.JsonMappingException: Can notat [Source: io.undertow.servlet.spec.ServletInputStreamImpl at 55dee6f8; line: 1, column: 119] (through reference chain: org.keycloak.representations.idm.ProtocolMapperRepresentation["co       at com.fasterxml.jackson.databind.JsonMappingException.from(JsonMappingException.java:270)                                                                                             at com.fasterxml.jackson.databind.DeserializationContext.reportMappingException(DeserializationContext.java:1234)                                                                     at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1122)                                                                       at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1075)                                                                       at com.fasterxml.jackson.databind.deser.std.StringDeserializer.deserialize(StringDeserializer.java:60)
Appreciate if anyone can advise on this (keycloak version is 3.4.3)
Thanks Jamie
