Get the substring of a field using Smart Values

[Stephen Schaff]

Automation for Jira has the awesome feature "Smart Values".  The documentation also shows several functions you can use with Smart Values.

The ones I am looking at are "left" and "lastIndexOf".

I have a "System Version" field that I need to take the value 3.51.2.12 and get 3.51.2. (To plug into a JQL query to get all values on a similar version.)

These two statements work fine:

{{issue.System Version.left(6)}}
{{issue.System Version.lastIndexOf(".")}}

 They give the answers you would expect.

However if I combine them like so:

{{issue.System Version.left(issue.System Version.lastIndexOf("."))}}

Then I get the following error:

Invalid character at 49. Must be '.' or end of line: left(triggerIssue.System Version.lastIndexOf("."))

I tried several syntax variations and can't find a way to make this work.  

Is there pass the results of one function as a parameter to another function? (or some other way to get the substring I am looking for?)

Have you tried the following:

{{issue.System Version.left({{issue.System Version.lastIndexOf(".")}})}}
