Setting different properties will retain the existing ones for this node. Note that a single value are submitted not as a map but just as a value (which is valid JSON) like in the example below.

This will replace all existing properties on the node with the new set of attributes.

This example shows the response you get when trying to set a property to null.

Figure 18.35. Final Graph

Example request

{
  "foo" : null
}

Example response

{
  "message" : "Could not set property \"foo\", unsupported type: null",
  "exception" : "PropertyValueException",
  "stacktrace" : [ "org.neo4j.server.rest.web.DatabaseActions.set(DatabaseActions.java:155)", "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:213)", "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:195)", "java.lang.reflect.Method.invoke(Method.java:597)" ]
}

Nesting properties is not supported. You could for example store the nested JSON as a string instead.

Example request

{
  "foo" : {
    "bar" : "baz"
  }
}

Example response

{
  "message" : "Could not set property \"foo\", unsupported type: {bar=baz}",
  "exception" : "PropertyValueException",
  "stacktrace" : [ "org.neo4j.server.rest.web.DatabaseActions.set(DatabaseActions.java:155)", "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:213)", "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:195)", "java.lang.reflect.Method.invoke(Method.java:597)" ]
}
