Unable To Send Email Report In VDP 6.1.4

This issue is applicable to 6.1.4 only. Here, you will be able to send a Test email, however, the scheduled email reports are not sent. In the vdr-server.log, you notice the following NullPointerException.

In the GUI you might see:
"Send email summary report error: Failed to send the email summary report. Reason: null"

vdr-server.log:

To fix this:

1. Download the zip file from this link here.
2. The md5 hash for this is: 90a57acb1404cdff68181b6768d3b539 Verify if this is the same on the downloaded zip
3. Use WinScp and copy this file to the /root folder of VDP
4. From SSH of the VDP appliance stop the tomcat service using:
# emwebapp.sh --stop

5. Backup the original vdr-server.war file using this command:
# cp -p /usr/local/avamar/lib/vdr-server.war /root/vdr-server.war_ORIG

6. Copy the patched binary using this command:
# cp /root/vdr-server.war /usr/local/avamar/lib/vdr-server.war

Make sure the permission for this patched binary is same as the original file.

7. Remove the vdr-server* files from tomcat using:
# rm -R /usr/local/avamar-tomcat/webapps/vdr-server*

There will be two files under this webapps directory for vdr-server. Verify before removing and these will be recreated once tomcat is restarted.

8. Start the tomcat service using:
# emwebapp.sh --start

9. The vdr server initialization takes a while and then you should be able to connect to VDP in web client and test your email reporting.

Or, you can download the script from github and run it on VDP to fix this automatically. Download vdp614-email-fix.sh

If this still does not work, open a case with VMware support. Hope this helps!
