Hi Team,

On 16/May/2020, we upgraded our jenkins from 2.165 to 2.236 version. After upgrade, we are getting an exception while sending an email after build Failure in Jenkins. It was working fine before upgrade.

Below is the exception message from jenkins console log. Please check this asap and resolve. Let us know if any details needed. Thanks.

 

Exception:

ERROR: Processing failed due to a bug in the code. Please report this to the issue tracker (https://jenkins.io/redirect/report-an-issue).
