I have a need to extract some JSON data, my postman data looks as follows 
JSON
"typeProperties": {
"format": {
"type": "JsonFormat",
"filePattern": "setOfObjects",
"jsonNodeReference": "$.[0].",
"jsonPathDefinition": {
"firstRecIdField": "firstRecIdField"
}
},
But the pipeline is failing with JsobReader item not an object, any ideas on how I should structure it in ADF?
Thanks in advance
