Trello api add PDF attachment will always return unsuccessful response

Question

Hi guys,

When I upload a pdf to a Trello card. the response will always include this:
```

bytes: null,

isUpload: false,
```

as if the upload failed. But the upload actually succeeded....
This only happens when I upload a pdf

I tried to play with the mime type I used: application/pdf, x-pdf, image/png

Does anyone know how to get the API to return a successful response?

Thanks in advance!

Update:
I figured it out. The file needs to be in a form using system.io.fileinfo. I'm on PowerShell 7 and I believe you might have to get into some .NET to make it work on PS5.1.

$FORM = @{
    idList     = "xxxxxx"
    pos        = "top"
    name       = "TestTest"
    fileSource = [system.io.fileinfo]"C:\Path\Path\File.pdf"
}

Invoke-RestMethod -Method Post -Uri "https://api.trello.com/1/cards?$APIKEY" -Form $FORM
