Script function failed on Automation for Jira rule: error: groovy.lang.MissingPropertyException: No

[Mouna Hammoudi]

I am using an automation for Jira rule to be executed once the user clicks on a button. I would like to automatically create some linked issues once the user clicks on the button but I receive the following error message:

 Script function failed on Automation for Jira rule: Script function failed on Automation for Jira rule: UpdateExecutionSummary , file: SuperFeature/rest_superFeatureGenerator.groovy, error: groovy.lang.MissingPropertyException: No such property: issueLinkType for class: SuperFeature.rest_superFeatureGenerator

How can I fix this?
