Configuring JSON TreeReader for accessing HW Schema Registry

JSON Tree reader and AvroRecordSetWriter are using :

Json Tree Reader:


Avro Record Set Writer:


Am I configuring the schema access wrongly?

Also, where can I get the correct URL for configuring the HWSchemaRegistry controller service? Is it the same link that I see in the Schema Registry UI?
