> The following example should return a value _abc_ but instead returns null

> spark.sql("""select get_json_object('{"k":{"value":"abc"}}', '$..value') as j""").show(){code}
> I checked the [spark test suite for Json expression parser | [spark/JsonExpressionsSuite.scala at f12793de205a46c75529ac20649e2e61edc0b144 · apache/spark · GitHub|https://github.com/apache/spark/blob/f12793de205a46c75529ac20649e2e61edc0b144/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/JsonExpressionsSuite.scala]] and the example there seems to be for a negative test case (non-existent key), so I'm not sure if this is expected.
