Adding custom fields to issues in a project with REST API

[Maulik Panchal]

I have created a few custom fields using an API call.
These fields were created successfully and I can view them on my Jira dashboard in Issues > Custom Fields.

When I call another API to create an issue within a project, I want to assign values to these custom fields.
I was able to get the custom field ID from Jira eg. customfield_10082

When I now call the API to add an issue with a structure like this -

{
"fields": {
"project":
{
"key": "ProjectKey"
},
"summary": "This is a Test Issue ",
"description": {
"type": "doc",
"version": 1,
"content": [
{
"type": "paragraph",
"content": [
{
"type": "text",
"text": "Test Description"
}
]
}
]
},
"customfield_10082": [{"key":"This is my custom field"}],
"issuetype": {
"name": "Task"
}
}
}

I get an error that says -
"Field 'customfield_10082' cannot be set. It is not on the appropriate screen, or unknown."

When I edit this field on Jira, I added it to all the 3 available screens -
Default Screen
Workflow Screen
Resolve Issue Screen

However, even after adding it to the 3 screens, I get the above error and I am unable to add the custom field to my issue.

I have seen some older threads on the same issue where it was mentioned that it was not possible to add these custom fields to a screen / project.

Eg. Here 

Is there any way in which I can achieve this?

I have created the custom fields previously, I now want to create an issue, and while creating it, add values to these custom fields in the issue.

Any help is appreciated.

Thanks !!

Hi @Maulik Panchal ,

The screens are a „ordered display list“ of fields. Those screens can then also be added to screen schemes which define which screen appears on a special operation (view, create, edit).

Could you confirm that you can see the field when you create a new issue manually within jira?

Best

This custom id might be already exist if you can try with some other Id. I think that will work. I am creating from Postman and I am able to successfully achieve this activity.
