 == Status description
+The graph type constraint is missing an alias.
 
+== Explanation
+Attempting to define a constraint against a node that is not using an alias, such as `:Node`, will cause this error.
+The constraint must be defined against an element type alias, for example, `n:Node`.
+
+== Example scenario
+Attempt to define an existance constraint as follows:
+
+[source,cypher]
+----
+ALTER CURRENT GRAPH TYPE SET {
+    CONSTRAINT FOR (:Node) REQUIRE n.prop IS NOT NULL
+}

+An error will be thrown with GQLSTATUS 22NCB and the status description:
+
+[source]
+----
+error: data exception - invalid element type constraints in graph type. A node element type property existence constraint cannot be specified inline of a node element type.

+
+A correct definition is as follows:

+[source, cypher]

+ALTER CURRENT GRAPH TYPE SET {
+    CONSTRAINT FOR (n:Node) REQUIRE n.prop IS NOT NULL
