Jira Automation : Using Two Smart Values Together

Rick Moerloos_ske60k

I have an automation that examines the Labels field values and builds a string based on found labels (ultimately, I want to remove those labels). The first challenge is that if I find fewer labels than the total number of labels, I end up with a trailing comma at the end of my string that I want to remove. 

So, I try to remove the last character from my string, as follows:

 

Smart Value: teamLabels (examines the labels field and builds up a string based on found values):

{{#labels}}{{#if(startsWith("team/"))}}{"remove": "{{.}}"}{{^last}} ,{{/}}{{/}}{{/}}

Problem is that this can leave a trailing comma if there are additional labels. So, I try to remove it. 

Smart Value: teamLen (gets the length of teamLabels - 1)

{{#=}}{{teamLabels.length()}}-1{{/}}

Smart Value: teamLabelsTrim (returns teamLabels with the last char removed)

{{teamLabels.left(teamLen)}}

I have tried multiple variations of the formula for teamLabelsTrim and either Automations can't parse it, or teamLabelsTrim comes back empty. I verified teamLabels and teamLen have appropriate values.

Hi @Rick Moerloos 

When I tested your first smart value expression for removing the teamLabels it did not leave any trailing commas for several test scenarios.

Would you please post an example where it did leaving a trailing comma? 

Also I recommend writing that expression directly to the audit log as that may confirm if the problem is the input (i.e., labels), the smart value expression, the JSON into which you are inserting that, or something else.  Without seeing your entire rule it is difficult to know.

Kind regards,
Bill
