Panel doesn't open a download file dialog

[sven-vm]

In my panel I download a file via a nodeJS URL. When I test this page via my browser, it visits the URL, downloads the file to the server, and then opens a filedialog window to ask you to place it.

script.js

////////////////////

// TODO: DOWNLOADING TEST //

////////////////////////

let btnDownload = document.getElementById("btnDownload");

btnDownload.addEventListener('click', function () {

window.location.href = 'http://localhost:3000/downloadmedia?productionid='+productionId+'&mediaid='+mediaId;

}

The nodeJS server code

// define a route to download a file

app.get('/downloadmedia/', async (request, response) => {

//Setup API client & connection

     //...

// Downloading file to server via API

//...

console.log("Downloading file to __dirname + /temp/: " + __dirname + "/temp/");

await mediaObject.download(__dirname + '/temp/');//Download file and place in temp folder

let file = mediaObject.structuredDescription.fileName; //mediaobject filename

console.log("Downloaded : " + mediaObject.structuredDescription.fileName);

let fileLocation = __dirname + "\\temp\\" + file; //Complete path

console.log("FileLocation = " + fileLocation);

//Send the download response, and browser asks user for location

response.download(fileLocation);

});

HOWEVER, when I click the same button but in the panel in Premiere Pro, the logs state that it still downloads the file correctly, but doesn't open a filedialog to ask the user for a location to place it to. How can I solve this?

Sorry, potentially ignorant question: Where does the value for _dirname come from? It seems like that isn't getting set correctly, in the panel case.

That should be part of Node.js

But you'll need to modify it anyway, because (in the example above) it's downloading into the extension's own directory. That'll work okay for an unsigned panel while debugging, but modifying the contents of an extension's directory will invalidate its signature, and make it no longer load.
