It seem that there are errors

you should change

{
    "packName": "My Modpack",
    "icon":
    {
        "path": "my-logo.png",
        "width": 64,
        "height": 64
    }
    "localVersion": "1.2.4"
}

by

{
    "packName": "My Modpack",
    "icon":
    {
        "path": "my-logo.png",
        "width": 64,
        "height": 64
    },
    "localVersion": "1.2.4"
}

and

{
    "packName": "My Modpack",
    "icon":
    {
        "path": "my-logo.png",
        "width": 64,
