Hello Team, I have one column and did some calculation on it and wanted to make another copy of same column to create flag to check whether records are empty or not and retain the same column also.I tired to using pulling another processor and wrote calculation New_field , Old_column which did not work. However, this approach did not yield the desired outcome.

Thank you @SAMSAL , I tried using JOLT, but when it didn't work, I resorted to using the UpdateRecords process. However, this is ultimately what I need.

Hello Team, I have JSON like following [ { "INTEGRATION_ID": "1", "ISSUE_STATUS_CAT": "Done", "SPRINT_LIST": [ "24-w1-2", "24-w1-3", "24-w1-4" ] },{ "INTEGRATION_ID": "2", "ISSUE_STATUS_CAT": "Done", "SPRINT_LIST": "24-w1-2" } ] My requirement is to check whether SPRINT_LIST is array or not. so I am using UpdateRecord processor with following formula ${field.value:startsWith(" [ ")} I was getting the correct output earlier, where it returned 'True' when the value was a list and 'False' when it was null or not a list. However, after making some changes and then reverting back to the original settings, I started encountering issues. "Cannot convert value [true] of type class java.lang.String to Object Array for field error"

Good day, everyone. This problem has been resolved. I made a new subfolder called /opt/nifi_server/ and installed the NIFI in it. When I first began, it gave me the error "Unable to bind the IP with port 844." I terminated the PID and launched the Nifi.Everything is back to normal now.
