Not able to create Epic using Jira Rest API

[Colombia.pos .]

I'm Using Jira rest API version 3, to create an issue type Epic by Below Post Request.

https://example.jira.com/rest/api/3/issue

but getting below error:

{
"errorMessages": [],
"errors": {
"customfield_11301": "Field 'customfield_11301' cannot be set. It is not on the appropriate screen, or unknown."
}
}

On my project, customfield_11301 maps to Epic Name which is already attached to the appropriate screen.

I'm Currently using administration access for API authorization. I have also provided all the high-level permission on the permission scheme attached to my project.

Please provide a solution to solve this issue.

Hi @Colombia.pos .,

Just to make sure you did check the correct screen. I usually do it like this:

• Go to the project settings
• Navigate to screens
• Expand the section which contains the Epic
• Click on the create screen for Epic
• Check if the field is on this screen

It happened often enough to myself that I checked the wrong screen.

Does your problem still exist? If yes, please also try if it happens with the API version 2 since v3 is still in beta.

Cheers,

Matthias
