I am failing to add image files to a photoscene in Autodesk's Forge API.

I have attempted this using two methods and both are failing, though each with a different error message:

Specifying the file using a URL:

json=`curl -v -s $FORGE_URL/photo-to-3d/v1/file \
        -H "Authorization: Bearer $forge_access_token" \
        -d "photosceneid=$photosceneid" \
        -d 'type=image' \
        -d "file[1]=http://cloud1.tri-di.com/scans/VG1.3/20200617191821/img01-cam00-USB+2.0+Camera+26.jpg" 

The above code generates the following error:

{
  "msg": "An error occurred while trying to copy the file",
  "code": "34"
}

Specifying the file using a local filename:

When I cd to the local directory containing the image files, I can specify the files[1] like this:

    json=`curl -v -s $FORGE_URL/photo-to-3d/v1/file \
    -H "Authorization: Bearer $forge_access_token" \
    -d "photosceneid=$photosceneid" \
    -d 'type=image' \
    -d "file[1]=img01-cam00-USB+2.0+Camera+26.jpg" 
`

then I am getting the following error message instead:

{
  "msg": "Specified image protocol is invalid",
  "code": "18"
}

Calling curl -v provides the following debugging information.

Has anyone else had a similar problem? How did you resolve it?

Instead of sending all info as data (-d flag), send it as a form content (-F flag):

curl --location --request POST 'https://developer.api.autodesk.com/photo-to- 3d/v1/file' \
-H "Authorization: Bearer $TOKEN" \
-F "photosceneid=$PHOTOSCENE" \
-F "type=image" \
-F "file[0]=http://cloud1.tri-di.com/scans/VG1.3/20200617191821/img01-cam00-USB+2.0+Camera+26.jpg"

I will report to engineering team to have documentation changed to reflect this approach.
