Error setting up email configurations in Jenkins

Question

I am getting Null pointer exception while configuring email notification in Jenkins.

I have made the required changes on gmail account. Have followed the steps exactly, but I still get below error when I test my configuration:

Test configuration ERROR A problem occurred while processing the request. Please check our bug tracker to see if a similar problem has already been reported.

I have found this answer from another post:

The latest mailer plugin version 1.24 has a bug, which causes test configuration failure(authentication required) even if you have the correct configuration. Download the 1.23 (.hpi file) version from Official website, then upload it from manage plugin->advanced. Restart jenkins, it should work well.

Only need to enable the less secure app access, there is no need to open 2-step verification.

If that is your problem go to the answer from tw Zhang and give a vote. I only would add that I have tried with plugin 1.25 and also fails

I upgraded mailer version and it worked for me.Thanks for your help. — user12046824, Sep 11 '19 at 09:00
