How can i set a labels type custom field using smart values in automation?

[Diane Fahr]

We have a labels type custom field called Market.  I am trying to copy from labels to market.  I have tried this method: 

and I tried ..

{
"fields": {
"customfield_12501": {{triggerIssue.labels}}
}
}

when i add a log statement for issue market: {{triggerIssue.Market}} only a blank is returned. 

How can I access this field?

Hi @Diane Fahr 

The labels field is a list of values, so perhaps trying converting it into a JSON array first, like this:

{
  "fields": {
    "customfield_12501": {{triggerIssue.labels.asJsonStringArray}}
  }
}

Kind regards,
Bill
