[keycloak-user] Error creating realm role with attributes

Hi everybody, I'm trying to create a realm role with custom attributes. When i make this POST request: /auth/admin/realms/master/roles with the following body: { "name":"test_user", "description": "im a test user", "attributes": { "color": "#555" } } I get the error: Cannot deserialize instance of `java.util.ArrayList` out of VALUE_STRING token And when i try the request with this body: { "name":"test_user", "description": "im a test user", "attributes": { "color": ["#555"] } } I get a 201 but the role is created without the color attribute. Thanks, Rafael.
