question NiFi JoltTransformJSON - Several Changes in Support Questions https://community.cloudera.com/t5/Support-Questions/NiFi-JoltTransformJSON-Several-Changes/m-p/310431#M224152 Hello,I am working with the JoltTransformJSON processor, which I consider to be very powerful but complicated to use and there is not much documentation about it.I have the following input JSON:  <LI-CODE lang="markup">{ "logTypeCode":"FIN", "eventNumber":"1", "eventTime":1568066703172, "eventInfo":{ "eventId":"CREATE_DOMESTIC_STANDING_ORDER", "eventVersion":"1" }, "operationInfo":{ "operationId":"DOMESTIC_STANDING_ORDER" } }</LI-CODE>   And my output JSON I need it to be the following:   <LI-CODE lang="markup">{ "body":{ "logTypeCode":"END_OF_TESTING", "eventNumber":"1", "eventTime":1568066703172, "eventInfo":{ "eventId":"CREATE_DOMESTIC_STANDING_ORDER", "eventVersion":"1" }, "operationInfo":{ "operationId":"DOMESTIC_STANDING_ORDER" } }, "header":{ "date":"${dateInPropertiesFlow}" }, "customValue":{ "logTypeCode":"END_OF_TESTING", "ENV":"${anotherPropertie}" } }</LI-CODE>    basically, I want to group everything that comes to me inside the "body" field, then I need to create another field that is called "header", which contains a single field called "date" with the value of a property that comes to me by the flow, and finally I need a field that is called "customValue", where the value "logTypeCode" has to have the same value as the field that is in "body.logTypeCode".I'm trying several ways in the application <A href="https://jolt-demo.appspot.com/#inception" target="_self">https://jolt-demo.appspot.com/#inception</A> but I can't get it to work as I want, for now this is the closest I got....    <LI-CODE lang="markup">[ { "operation": "shift", "spec": { "*": "body.&" } }, { "operation": "default", "spec": { "header": { "date": "${paramDate}" } } } ]</LI-CODE> I've been doing a lot of tests, but I can't get the result I need... Help! Thanks Tue, 26 Jan 2021 12:48:20 GMT calonsca 2021-01-26T12:48:20Z
