Scriptrunner scripted field import error

[Dawn Rodney]

I'm attempting to use the "Total time this issue has been In Progress" script to add a field to the tickets in a specific Jira Project. After I fill out the necessary fields in the Add New Scripted Fields form, I copy the script and click the Test button. This is the error I get. Any ideas on how I can resolve this?

Error

An error occurred whilst running the scripted field.

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: Script1.groovy: 1: unable to resolve class com.atlassian.jira.component.ComponentAccessor @ line 1, column 1. import com.atlassian.jira.component.ComponentAccessor ^ Script1.groovy: 2: unable to resolve class com.atlassian.jira.issue.history.ChangeItemBean @ line 2, column 1. import com.atlassian.jira.issue.history.ChangeItemBean ^ 2 errors at com.adaptavist.sr.cloud.workflow.AbstractScript.parseScript(AbstractScript.groovy:48) at com.adaptavist.sr.cloud.workflow.AbstractScript.evaluate(AbstractScript.groovy:31) at com.adaptavist.sr.cloud.events.ScriptedFieldExecution.run(ScriptedFieldExecution.groovy:30) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at TestScriptedFieldExecution1_groovyProxy.run(Unknown Source)

Thanks for your help!
