@jpercivall and @mclark Thank you both! I see the Response actually contains the content. Thanks much! . ... View more

@jpercivall Hey, got a follow up question-- InvokeHttp Original does not output any content. It should output whatever get from the url, correct? Data provenance content tab shows "Replay: Cannot replay data from Provenance Event because the event does not contain the required Content Claim". Do you know what is the problem for that processor configuration? Thanks! Shannon ... View more

@mclark The URL string includes a number of parameters. One of the parameters needs to be changed. UpdateAttribute is used to change the parameter value, which is a variable in URL string. The problem is that GetHTTP doesn't allow incoming connection from UpdateAttribute. Is there any other way of achieving the same? Thanks, Shannon ... View more

@Chris Gambino Hey Chris, Thanks for the help! A follow up question-- what processor would it take to call the new attribute and add to the flowfile before sending to PutFile? It can't be MergeContent, right? couldn't find anything like union. Thanks again! Shannon ... View more
