I am getting the error while using "com.atlassian.jira.ComponentManager" how to resolve this.

Hello @Nivetha Ganapathy ,

Check out the following threads that go into a bit more detail, but this error usually happens in relation to an outdated class in a scripted function post upgrade on Jira Server, most commonly in a Groovy Script:

• https://community.atlassian.com/t5/Jira-questions/unable-to-resolve-class-com-atlassian-jira-ComponentManager/qaq-p/1054443
• https://community.atlassian.com/t5/Jira-questions/Groovy-script-no-longer-works-after-JIRA-upgrade/qaq-p/1026139

So first question about this would be, Are you on Jira Serve, as it looks like this thread was flagged as Jira Cloud for the platform, so I just wanted to verify if this is the case.  Also, how are you triggering this and where are you seeing the error? Basically, are you calling "com.atlassian.jira.ComponentManager" in a custom groovy script as discussed in the threads above, or is this occuring somewhere else in the application?

Regards,
Earl
