Hi @Aisha M

Probably for some events, an attribute is null and your code tries to get a substring of that null attribute. I think it is best to add a null check.

If you share your code, I'll try to correct the problem.

Thank you for the prompt help :)

The above highlighted lines show an error on the console (but the script works fine anyway)

1ST ONE - Cannot find matching method. com.atlassian.jira.issue.Issue#setAssignee(com.atlassian.jira.user.ApplicationUs
Please check if the declared type is correct and if method exists

2ND ONE - Cannot find matching method.
com.atlassian.jira.issue.IssueManager#updateIssue(com.atlassian.jira.user.Application
com.atlassian.jira.issue.Issue,
com.atlassian.jira.event.type.EventDispatchOption, boolean).
Please check if the declared type is correct and if method exists

These logs are different from what you mentioned above.

The problem here is with the code belove

String userValue = cFieldValue.substring(cFieldValue.indexOf("<")+1 , cFieldValue.indexOf(">"))

The custom field value 'cFieldValue' can be null and you can't do an operation with a null value. So, you have to check if it has a null value. If you want to skip if that value is null simply put this line

if (!cFieldValue) return
String userValue = cFieldValue.substring(cFieldValue.indexOf("<")+1 , cFieldValue.indexOf(">"))

Let's fix this part first!
