Could not load class , so i don't go next step

[sooji na]

Hi
I did upgrade jira version 4.2.1 to 6.2.3
i have some questions.

When i click a button, An error has occurred.

• Could not load class 'com.iamhuy.jira.plugin.workflow.AssignFromCustomfieldFunction'

Therefore, it is impossible to proceed to the next step.

please help me , thank you

Your upgrade has missed out, or dropped, or disabled (because it's not compatible?) a plugin that provides "assign from custom field".

Probably this one, although all I've done is google the class name: https://marketplace.atlassian.com/plugins/com.iamhuy.jira.plugin.issue-alternative-assignee

Try installing/upgrading that plugin and retry.

It is that one.
