Bad Request: One or more of the contents is not owned by the author. All contents must be owned by the author

Question

I've been trying to POST an image to linkedin via the API given by linkedin: https://api.linkedin.com/v2/ugcPosts

Here are some of the steps I followed according to their documentation:

Step 1: Register the image,

Response I get:

{
    "value": {
        "mediaArtifact": "urn:li:digitalmediaMediaArtifact:(urn:li:digitalmediaAsset:C4D22AQHnSETazVUUiw,urn:li:digitalmediaMediaArtifactClass:feedshare-uploadedImage)",
        "uploadMechanism": {
            "com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest": {
                "uploadUrl": "https://api.linkedin.com/mediaUpload/C4D22AQHnSETazVUUiw/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQKy8KTj9ZExhAAAAYUvD_6GEclpKOZdwJvPF682Ld1UUb6h0V7VvAtpuA&app=206373578&sync=0&v=beta&ut=3dh6EETZGM5WA1",
                "headers": {
                    "media-type-family": "STILLIMAGE"
                }
            }
        },
        "asset": "urn:li:digitalmediaAsset:C4D22AQHnSETazVUUiw",
        "assetRealTimeTopic": "urn:li-realtime:digitalmediaAssetUpdatesTopic:urn:li:digitalmediaAsset:C4D22AQHnSETazVUUiw"
    }
}

Step 2: Upload the image using upload URL from Step 1 Response: 201 Created status code with no message

Checked the status, it's says available: https://api.linkedin.com/v2/assets/C4D22AQHnSETazVUUiw

{
    "recipes": [
        {
            "recipe": "urn:li:digitalmediaRecipe:feedshare-image",
            "status": "AVAILABLE"
        }
    ],
    "serviceRelationships": [
        {
            "relationshipType": "OWNER",
            "identifier": "urn:li:userGeneratedContent"
        }
    ],
    "mediaTypeFamily": "STILLIMAGE",
    "created": 1671531855410,
    "id": "C4D22AQHnSETazVUUiw",
    "lastModified": 1671531901231,
    "status": "ALLOWED"
}

Now when I am trying to POST it to the endpoint: https://api.linkedin.com/v2/ugcPosts

It's giving 400 bad Request with the following Error:

{
    "errorDetailType": "com.linkedin.common.error.BadRequest",
    "message": "com.linkedin.content.common.exception.BadRequestResponseException: One or more of the contents is not owned by the author. All contents must be owned by the author",
    "errorDetails": {
        "inputErrors": [
            {
                "description": "Content(s) you provided must be owned by post author",
                "input": {},
                "code": "INVALID_CONTENT_OWNERSHIP"
            }
        ]
    },
    "status": 400
}

I've given all permissions to it:

r_emailaddress, r_liteprofile, w_member_social
