Script Runner: validate field of an issue linked when creating issue

[Ignacio Downey Fernandez]

Hi Everyone,

We need that when creating a JSM request, do the following:

• Link an issue that meets the values ​​of a custom field - Done (with an automation branch)

•  Show a validation error when the linked issue custom field date is greater than 72 hrs in relation to the current date.

I have not been able to do this validation and I am trying to see how I could do it through ScriptRunner transition validation. Could someone help me with this solution.

Thanks
