Hi @Raj Kumar 

the reason why you're getting this error is because you've typed a Groovy script instead of a Jira Expression. Groovy is used on Jira Data Center, whereas Jira Cloud only supports Jira Expressions, an Atlassian-made language.

You can use the Jira Expressions "match" method of strings instead:

issue.customfield_12345?.match('^\w+$')
