Jira Select List value not getting Updated

[Hemanshu Sood]

Hi all,

I had created a script to update a select list in Jira from an existing value to a new one.

Unfortunately , the select list value is not getting updated, while there are no errors in logs, please suggest:

def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
log.error("User: $currentUser")
if (ComponentAccessor.getUserUtil().getGroupNamesForUser(currentUser.name).contains("Custom Group"))
{
def cfSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Select List ")
def cfConfig = cfSelect.getRelevantConfig(issue)
def value = ComponentAccessor.optionsManager.getOptions(cfConfig)?.find {
it.toString() == 'REJECTED'
}
issue.setCustomFieldValue(cfSelect, value)
}

Now getting below error:

groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method com.atlassian.jira.issue.fields.CustomFieldImpl#getRelevantConfig.
Cannot resolve which method to invoke for [null] due to overlapping prototypes between:
 [interface com.atlassian.jira.issue.Issue]
 [interface com.atlassian.jira.issue.context.IssueContext]
 [interface com.atlassian.jira.issue.context.JiraContextNode]
 at Script168.run(Script168.groovy:10)

Any help would be appreciated
