hello everyone I am trying to create a sink (httpSink to be specific) using this api /admin/v3/sinks/${tenant}/${namespace}/${name} I have escaped the JSON object to form data area but now getting a different error

{ reason: 'Sink package is not provided' }

please guys how do I add package to my payload as there is no such key in the documentation https://pulsar.apache.org/sink-rest-api/?version=3.0.0#operation/SinksBase_registerSink
