I'm trying to upload a video following this Graph API documentation: https://developers.facebook.com/docs/video-api/guides/publishing

I have been able to upload the video and received a video handle in response.

However, no matter what I try, when doing the final "publish" step, I get this response:

{
    "error": {
        "message": "There was a problem uploading your video file. Please try again with another file.",
        "type": "OAuthException",
        "code": 6000,
        "error_data": {
            "error": null
        },
        "error_subcode": 1363019,
        "is_transient": false,
        "error_user_title": "Video wasn't uploaded",
        "error_user_msg": "There was a problem with uploading your video. Please wait a few minutes and try again.",
        "fbtrace_id": "AMa9zbs8h3b4omv5wRSfTsf"
    }
}

Things I've tried: - Making POST request via Facebook Javascript SDK - Making POST request via axios - Making POST request via axios via CORS proxy - Making POST request via the Graph API Explorer - Making POST request from a vercel.app host rather than localhost - Posting a variety of video file types and sizes

Every time, exactly the same response (fbtrace_id changes)

Needless to say, the error message isn't giving me enough information to find the cause of the problem (and waiting a few minutes and trying again later doesn't help).

The request that is being made (via Javascript SDK) is:

curl 'https://graph.facebook.com/v20.0/365492213311492/videos?access_token=<PAGE_ACCESS_TOKEN>' \
  -H 'accept: */*' \
  -H 'accept-language: en-GB,en-US;q=0.9,en;q=0.8' \

I suspect the problem has to do with permissions and the Facebook app configuration. I tried to post just a regular Page Post and that was successful. The successful Page Post request was:

curl 'https://graph.facebook.com/v20.0/365492213311492/feed?access_token=<PAGE_ACCESS_TOKEN>' \

Other contextual information

• The Facebook App has not undergone App Review yet, but the User is connected to the Facebook App, so that shouldn't be a problem
• The User has admin access to the test Page

• Based on the user access token and the page access token, the permissions are: (same for both)

  • email
  • publish_video
  • pages_show_list
  • pages_read_engagement
  • pages_read_user_content
  • pages_manage_posts
  • pages_manage_engagement
