Updating single select custom field with automation for Jira

[Nikki Zavadska _Appfire_]

Hi 👋 ,

I'm trying to create automation that updates the custom field that I created with an option from that custom field.

The JSON I'm using to update is:

{
"fields": {
"customfield_10121": { "value": "b" }
},
}

(I figured this based on the documentation here: https://support.atlassian.com/cloud-automation/docs/advanced-field-editing-using-json/ 

This is how my custom field values look like in the GET issue api:

The values that are available in the dropdown for this field are a and b

When I run the automation I get the following error:

Error while parsing additional fields. Not valid JSON.

I can't see what I'm doing wrong here, I tried many options already but can't figure it out. Did anyone have a similar problem and find a solution?

I create in a postfunction of a Create Transition several other Issues (all different regular issue type). In order to achieve this I use the Exocet plugin.

So, I guess you could do something similar in your case. However there is a lot of configuration to do.

Under 4.4 this plugin was named LNIO but I'm not sure if this has the full capability regarding your requirement. But please look for your self.
