Hello, Did you solve this issue? Does your readings works well with NiFi from the Modbus device? ... View more

You can handle the errors or outputs better with the custom processor approach. ... View more

@mburgess Helpful information shared. I am using Nifi 1.7.1 For my case, the incremental fetching does not seem to work correctly. All records gets ingested from the database but do not make it all the way to the destination. Processor used is GenerateTableFetch then Execute SQL and the other corresponding processors down the data processing flow. Record id is captured correctly on the GenerateTableFetch property state and its up to date as the record id from the  source (db). However, it will still miss some records when processing the files making the number of records on the destination out of sync with the source from the db. Am i missing something, Would scheduling times for fetching help and how can I do that? ... View more

Thanks,Matt! Sorry for a late answer 🙂 ... View more

You need to give an attribute to the response object by clicking to + sign. The processor must be stopped to add an attribute. Then response is HTTP/1.1 200 OK Date: Tue, 26 Feb 2019 13:27:12 GMT Content-Type: xml Transfer-Encoding: chunked Server: Jetty(9.4.3.v20170317) You may also look at another anwser here https://community.hortonworks.com/questions/86964/setting-custom-http-headers-with-handlehttprespons.html ...
