Hi, I am fetching some HQL files from GitHub using InvokeHTTP processor and executing the SQL using PutHiveQL processor. The challenge is that the HQL files are having reference of some nifi attributes and those attribute values are not getting populated but those attributes are present in the flow file. Example: HQL file content: select * from tbl_sales where load_date='${load_date}';   InvokeHTTP processor response: select * from tbl_sales where load_date='${load_date}'; My understanding is that once the response comes to nifi then it renders the flow file content and it should automatically populate the date value (eg. '2021-04-14') instead of the string reference i.e. '${load_date}'.    I need your expertise to confirm if it is the expected behaviour of nifi that it should only be getting the HQL content as it is and not rendering it to the actual attribute value. If not then can somebody please help how to get this attribute value populated?   Here is the screenshot of the flow:   Thanks!   ... View more
