Edit "Request Language" Custom Field through Automation for Jira

[Kaur Joakit]

Hi!

We are receiving requests in two ways - via e-mail and via API (from external source/website). We do not use Customer Portal for this particular project.

We set up automation below:

So, whenever Reporter's e-mail address ends with .nl, Automation should send e-mail, edit Country field and edit Request Language to "Dutch". 

Unfortunately receiving errors related to Request Language change. It simply is unable to change it. I have tried to use multiple other commands ("add", "edit", "update") besides "set", but still received errors:

{ 
"set": {
"customfield_15712" : { "value": "Dutch" }
}
}

What should be the proper command for it?
