Issue with http-notification service
Hello NiFi Team,
I am trying to setup NiFi lifecycle notifications in the bootstrap.conf
file. But instead of sending email notifications I want to send
notifications on slack so I thought of using http-notification.
I have configured the bootstrap-notification-services.xml with the slack
webhook url but it fails to send notifications. When I mention url with
https it throughts the following error:
2018-06-12 21:29:04,791 ERROR [Notification Service Dispatcher]
o.a.n.b.NotificationServiceManager Failed to send notification of type
NIFI_STOPPED to HttpNotificationService[id=http-notification] with Subject

Anyone have any idea how I can get this to work or do I have to stick with
email.
One workaround I can think of is to setup a flow to listen to HTTP on the
canvas and pass it to PutSlack processor but I do not want to do that as it
will be unnecessary one more dependency.
Kind Regards,
Raman

Hi Raman,
Since you're using 'https' endpoint, I believe you need to configure
HttpNotificationService with trust store settings.
The NullPointerException can happen if OkHttpClient is null when the
notification service tries to send notifications, that can happen if
OkHttpClient is not initialized correctly. I assume there is another
error log message prior to the NPE.
Please check out this documentation on what properties you need to set
such as 'Truststore Filename'
https://nifi.apache.org/docs.html
Thanks,
Koji

Re: Issue with http-notification service
Posted by Ramaninder Singh Jhajj <jh...@gmail.com>.
Hi Andy,
I am using version 1.6.0 as a single instance on my local MacBook pro.
The configuration of bootstrap-notification-services.xml file is:
<service>
<id>http-notification</id>
<class>org.apache.nifi.bootstrap.notification.http.HttpNotificationService</class>
<property name="URL">
https://hooks.slack.com/services/ID_OF_THE_SLAC_WEBHOOK</property>
</service>
Can it be due to slack url being https?
I am still not able to figure it out. So any help will be really useful.
Kind Regards,
Raman

Hi Raman,
What version of Apache NiFi are you using? In current master, that line (HttpNotificationService.java:228) is a blank line [1]. Can you also share the contents of your bootstrap-notification-services.xml file (redacting sensitive information if necessary)?
