Field 'CustomField_10136' cannot be set. It is not on the appropriate screen, or unknown.

[Bjarke Røjgaard Jensen]

Hi

I am creating af custom form in another system to create JIRA issues and to do so i use the Rest API, which i have used multiple times with great success.

I am facing a very strange issues. I recently added a custom select field to the default Jira screen of our service desk project. When i try to create an issue through the API where i include the custom field, i get the following error: "Field 'CustomField_10136' cannot be set. It is not on the appropriate screen, or unknown.". I've read a couple of post adressing this issue, but none of them gives a viable solution.

• The field is visable and editable on the screen. I've actualy added the field to all screens in the project..
• The API Key is created with a global admin account and the account has access to all screens and has can create issues and set this field in the portal.

I have done the exact same thing for another customer without any issues.

I use the following endpoint and json. If i remove "CustomField_10136" it is succesfully created.

$"{CustomerUrl}/rest/api/3/issue/{key}"

I am using the "customfield_10058", however getting the same error. What can be the reason. Same code is working with different Project however it is giving error for another project. Tried from Postman too, however getting same error:

{

    "errorMessages": [],

    "errors": {

        "customfield_10058": "Field 'customfield_10058' cannot be set. It is not on the appropriate screen, or unknown."

    }

}

Hi @[deleted] , welcome on the community. Most of the time it means you do not have your field on "Edit" screen. Check https://confluence.atlassian.com/adminjiraserver/defining-a-screen-938847288.html "Edit screen's details".

Wow @Martin Bayer _MoroSystems_ s_r_o__  I owe you a beer, been struggling with the customField for the last few hours...

For those attempting to set a custom field of type labels through the REST API that are getting this issue. Try moving the configuration outside of the fields key and into update, like so:

```
{
"fields": {
// your other fields
},
"update": {
"customfield_10029": [
{ "add": "ANY_VALUE" }
]
}
}
```

That did the trick for me.
