Had the same issue. Found when using postman app and doing authentication by hand that the Innovator Server (2024) does not like the Content-Type to be multipart/form-data. Seems to only work when it's "application/x-www-form-urlencoded". The getOAuthToken(creds) function sets up the var token_body as a FormData object ... when the http request eventually gets made, that FormData object will cause the Content-Type to be multipart/form-data. Which will faill with Error 400. Fix is to manually set the header and use a string for token_body.

In the getOAuthToken(creds) ... REMOVE:

    // build the OAuth token request
    var token_headers = [];

    var token_body = new FormData();
    token_body.set("grant_type", "password");
    token_body.set("scope", "Innovator");
    token_body.set("client_id", "IOMApp");
    token_body.set("username", creds.user);
    token_body.set("password", creds.pwd);
    token_body.set("database", creds.db);

and REPLACE it with:

    // build the OAuth token request
    var token_headers = [
        { name: 'Content-Type', value: 'application/x-www-form-urlencoded' }
    ];

    // Example URL-encoded token body
    var token_body = 
        "grant_type=password" +
        "&scope=Innovator" +
        "&client_id=IOMApp" +
        "&username=" + encodeURIComponent(creds.user) +
        "&password=" + encodeURIComponent(creds.pwd) +
        "&database=" + encodeURIComponent(creds.db);

Authentication succeeded after that.

Thanks, @gwagner613
That removed the authentication issue.

Unfortunately, uploading of the selected file fails with the following message:
Warning! 500 (Internal Server Error) from http://localhost/InnovatorServer/vault/odata/vault.CommitTransaction
