Having issues flattening the nested array in an array of objects back to its parent.   Given this JSON :    [ { "id": "13", "uom": "EA", "name": "pOne", "display_name": "displayOne", "brand": "brandOne", "categories": [ { "level1": "cLevel1", "level2": "cLevel2" } ] }, { "id": "87", "uom": "EA", "name": "pTwo", "display_name": "displayTwo", "brand": "brandTwo", "categories": [ { "level1": "cLevel1", "level2": "cLevel2" } ] } ]     I want to transform to this:   [ { "pName" : "pOne", "pBrand" : "brandOne", "pVariant" : "displayOne", "pSku" : "13-EA-000", "categoryHierarchy" : "cLevel1/cLevel2" }, { "pName" : "pTwo", "pBrand" : "brandTwo", "pVariant" : "displayTwo", "pSku" : "87-EA-000", "categoryHierarchy" : "cLevel1/cLevel2" } ]     So far I have these specs:   [ { "operation": "modify-default-beta", "spec": { "*": { "productSku": "=concat(@(1,id),'-', @(1,uom),'-000')", "categories": { "*": { "category": "=concat(@(1,level1),'/', @(1,level2))" } } } } }, { "operation": "shift", "spec": { "*": { "name": "[&1].pName", "brand": "[&1].pBrand", "display_name": "[&1].pVariant", "productSku": "[&1].pSku", "categories": { "*": { "category": "[&1].categoryHierarchy" } } } } } ]   It is however putting ALL the category values into a single array in the first object in the list, rather than in each respective object:   [ { "pName" : "pOne", "pBrand" : "brandOne", "pVariant" : "displayOne", "pSku" : "13-EA-000", "categoryHierarchy" : [ "cLevel1/cLevel2", "cLevel1/cLevel2" ] }, { "pName" : "pTwo", "pBrand" : "brandTwo", "pVariant" : "displayTwo", "pSku" : "87-EA-000" } ]     What Am I missing?   Thank you 🙂 ...
