Hello, 

The problem is that your variable componentManager is unknown.

it shoud be 

issue.getCustomFieldValue(ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("<Field Name> "))

But you would need to make an import

import com.atlassian.jira.component.ComponentAccessor

Thanks Alexey, Could you please suggest that how can we import library in the email section. 

[Alexey Matveev]

<Field Name> <% out << issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("<Field Name> ")) %>

Tried, still getting the same error.

Please if you can suggest more solutions.

Thanks in Advance.

What do you pass for <Field Name> ? Make sure the field really exists

[pooja chourasia]

Required Order Contract Term (in months): <% out << issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Required Order Contract Term (in months)")) %>

Required Order Contract Term (in months) -  It's a field

[Alexey Matveev]

Somehow the field is not found in your Jira instance. Or the error is actually different

Hello Alexey

The issue was with the field only, re-indexing has fixed this issue.

Many Many Thanks for Your help :)
