ScriptRunner - Set a select list custom field value

[MIN_MWO012]

I need to update a select list (single choice) custom field as part of a workflow transition so I have tried the code provided in the link below

https://docs.adaptavist.com/sfj/set-a-select-list-custom-field-value-11468840.html

Unfortunately I get the error message below

Does anyone know how to fix this?

My code is

import com.atlassian.jira.component.ComponentAccessor

def cfSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("Change Request Priority")

def cfConfig = cfSelect.getRelevantConfig(issue)

def value = ComponentAccessor.optionsManager.getOptions(cfConfig)?.find {

    it.toString() == '5 - Urgent'

}

issue.setCustomFieldValue(cfSelect, value)

We are using Jira Software Data Center 8.20.8 and ScriptRunner 7.1.0

Thank you for your help

Your error is on this line:

def cfSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("Change Request Priority")

Notice the 's' in getCustomFieldObjecsByName 

This, and the error message indicating that a "getRelevantConfig"  is no application to "Collection" means that you have a collection of custom fields. Not a single custom field object

Change that line to

def cfSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("Change Request Priority")[0]

 But also, it's better to use an explicit method/property to compare objects rather than the generaic "toString"

Here is a fully revised version of your script:

import com.atlassian.jira.component.ComponentAccessor
def cfSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("Change Request Priority")[0]
def cfConfig = cfSelect.getRelevantConfig(issue)
def value = ComponentAccessor.optionsManager.getOptions(cfConfig)?.find {
    it.value == '5 - Urgent'
}
issue.setCustomFieldValue(cfSelect, value)

Dear @PD Sheehan 

Thank you for your help. It is highly appreciated. 

I will test the new script as soon as possible.

Worked nicely for me too.
