Hi, I want to change the flowfile content (json format) using UpdateRecord by providing property (to be change) from attribute. Here is the flowfile content here is the flowfile attribute I want to change the value of "id" in flowfile content using UpdateRecords like this : ( WHICH IS NOT WORKING ) This works but add a new property to existing flow file Here "id" got change because i provided "/id" (hardcoded property name) , i need same functionality to work with "/${col_name}" Any Pointers ... ????? Thanks, Riyaz

I got the Solution. Use UpdateAttribute processor and Expression Language. Here "SignedURL" is the attribute (containing complex Json) and from that I fetch particular Key value using Expression Language (JSONPATH)

@saquibsk Thanks for Reply. Solution you have provided will work with content of flow file and not with the attribute. EvaluateJsonPath is use to evaluate the JSON present in flow file content. In my case , I have JSON present as attribute and not as content of flow file.

How to Evaluate attribute (output of Invoke Http which is in JSON format) This attribute value contain a Json in the following format { location : { FileSource : "X" , URL : "Y"} } From this attribute value (Json), I need to extract File Source and URL and put it into another attribute with the same name. Note : Flow file Content should remain as it is. Any Pointer ..??

I am able to solve the problem Access token Rest API generates two token (check under cookies) - Secure-Request-Token and other is Secure-Authorization-Bearer token. While calling any of the other API (like creating Parameter Context or updating Parameter context) - in Headers provide one more header "Request-Token" with the value of _secure-Request-Token (From cookies).

For that , following API is used https://localhost:8443/nifi-api/parameter-contexts/2ddc0cea-018e-1000-3852-3611d730f705/update-requests Where "2ddc0cea-018e-1000-3852-3611d730f705" is the Id of parameter context. Issue : I tried to update the ParameterContext using https://localhost:8443/nifi-api/parameter-contexts/2ddc0cea-018e-1000-3852-3611d730f705/update-requests but its throwing 403 error .
