Can Automation for JIRA target the end date of a sprint?

Question

I am trying to set up the following Workflow in Automation for JIRA.

When the value changes for the Sprint field

Then add the sprint's end date to the field "Due date"

Here is the custom field.

"customfield_10301":[

"com.atlassian.greenhopper.service.sprint.Sprint@487c3460[id=592,rapidViewId=289,state=ACTIVE,name=Ca$htime,goal=,startDate=2017-01-09T19:53:52.703Z,endDate=2019-01-21T02:53:00.000Z,completeDate=<null>,sequence=592]"],

I was thinking it would work if I tried

but that did not work.

Hey @Haddon Fisher, I have not unfortunately. We didn't end up needing this in the end.

Hey @Chris Fadell did you ever get an answer to this? I am in quest of the same thing. Despite the field showing up as that long string in the API, all I get when I try to output the field in a comment is the sprint name, so I don't know that the string functions would even work here.
