I am looking to update the description of an issue on a transition with a post function.
The goal is to replace a certain piece of the url with the {{issue.summary.charAt(2)}} from the original ticket summary.
Example: Insert this into the description with the post function the value of the field set to: www.website.com/{{issue.summary.charAt(5)}}/issue
The outcome I would expect from a Issue Summary: Test 3 would be www.website.com/3/issue
but the description is updated and does not convert the smart value. sting www.website.com/{{issue.summary.charAt(5)}}/issue
Any ideas on how to make this execute and fill in the correct number from the summary or other workaround
