Attempting to import a craft entry json export throws FieldNotFoundException

[sebastiannoell]

Description

Every time I try to import a local file (entries), it fails throwing Field not found – Craft\errors\FieldNotFoundException when reaching admin/feed-me/feeds/map/1 route. Background: I would like to partially import entries from one craft instance to a fresh one. From the source instance I exported an entry as json which I am now trying to import to the target instance.

Steps to reproduce

1. Export an entry as json (also tried xml, same issue)
2. Save that json to a local folder that craft has access to
3. Try to re-import it
4. Confirm data got parsed correctly in route admin/feed-me/feeds/element/1
5. When clicking Save & Continiue, the error gets thrown.

Additional info

• Craft version: 5.8.17
• PHP version: 8.4.10
• Database driver & version: MySQL 8.0.43
• Plugins & versions: Feed Me 6.10.1

PT-2898 Attempting to import a craft entry json export throws FieldNotFoundException

[sebastiannoell]

Note: Even attempting to import this json will throw the same exception:

[
  {
    "postDate": "2025-09-05T04:45:00-07:00",
    "title": "Test News Entry",
    "slug": "test-news-entry",
    "uri": "news/test-news-entry",
    "dateCreated": "2025-09-05T02:47:24-07:00",
    "dateUpdated": "2025-09-05T04:45:26-07:00"
  }
]

When downgrading to Craft 5.8.12, I can get to the mapping route and the error does not get thrown. So it has to be related to that issue: craftcms/cms#17713

I think I have the same problem.
Setting up a new feed I don't get to the mapping page. When I try and 'save & continue' after selecting the Primary Element I get the error page heading of 'Field not found – craft\errors\FieldNotFoundException'
Craft 5.8.17 and Feed-me 6.10.1
I see it's been accepted as a bug, but no one assigned to it.
I can't move on with the new site I'm building if I can't import the content from the old site.

Hi All, thanks for reporting! I raised a PR for this.
