@pk87 ,

 

The HandleHttpRequest processor will only produce a flowfile when an HTTP call is received on its port. If you want this to be called every 60 minutes you can add an InvokeHTTP processor, scheduled to run every 60 minutes, that will call your API endpoint in the same way that Postman does.

 

You actually don't need the HandleHttpProcessor to run this on a regular basis. You could possibly replace that with a GenerateFlowFile that executes every 60 minutes and will trigger the process for you.

 

Cheers,

André

Above was discussed in another post here:
https://community.cloudera.com/t5/Support-Questions/NIFI-I-m-getting-issue-like-quot-authentication-details-were/td-p/346593
A configuration change was provided to resolve the http 400 response.  The new response was an HTTP 401 so request was good, but a end point did not like the authorization provided in the request.

Thanks

Matt

Also consider that using timer driven may not always give you 60 minute scheduling.  When using timer driven the component will get scheduled upon start and then again x configured amount of time later.  A NiFi restart or stopping and starting the processor will reset this.  If you need to make sure that a component is only scheduled every x amount of time consistently, you should be using cron driven scheduling strategy which will allow you to set specific time of schedule.

Thanks,

Matt
