[keycloak-user] Direct Access to KeyCloak

I am trying to write a test harness for out application which uses KeyCloak. In order to run my tests I need to manipulate KeyCloak. I am able to get data out of KeyCloak using the REST API. However I am unclear what I should send to KeyCloak to change a setting. I was trying to set the role for a user and wrote the script at the bottom of the email. I get back an error of org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of java.util.ArrayList out of START_OBJECT token at [Source: io.undertow.servlet.spec.ServletInputStreamImpl@73cda37e; line: 1, column: 1] I have obviously missed a key point in the format of my data, but cannot see what it is.
