Updating jira custom fields

[Irem_Odemis]

Describe the issue/error/question

Hey community, I’m stuck in one workflow where I want to update my custom fields in Jira node. For that I found the custom field id and I’m trying to write an expression to do the job.

The custom field looks like this

I wrote the value like this:
{{ { “self”: “https://hellofresh.atlassian.net/rest/api/2/customFieldOption/14318”, “key”: “OMGS-1”, “id”: “181004” } }}

I’m not sure if my expression is wrong or actually its another error because when I execute I get this message:

Can anyone guide me please?

{

“instanceId”: “bd3424651820da96219b3bf8bf1cdfabcd2b0cc2dbde58159a106ccfa63cca09”
},
“nodes”: [
{
“parameters”: {
“operation”: “update”,
“issueKey”: “={{ $json["key"] }}”,
“updateFields”: {
“customFieldsUi”: {
“customFieldsValues”: [

“fieldValue”: “={{ { "self": "https://hellofresh.atlassian.net/rest/api/2/customFieldOption/14318\”, "key": "OMGS-1", "id": "181004" } }}"
}
]
}
}
},

“credentials”: {

“name”: “Global Jira Account”
}
}
}
],
“connections”: {}
}

What is the error message (if any)?

That error suggests a problem on the Jira side. Are you sure the custom field is visible in the edit issue screen for that project? You can often tell if this is the case because the field won’t show in the drop-down list, you shouldn’t have to put the custom field in manually.
