Issue with "Choose a destination folder" Window

Simple import function as part of a larger prep script: all is functioning except I can't seem to get the value of the secondary pop-up window when importing audio -- where you choose the folder for the audio to be copied to. Anyone know why this (Line 36) isn't working?

function importAudio() {

//Refresh Cache
sf.ui.proTools.mainWindow.invalidate();
//File, Import, Audio
sf.ui.proTools.menuClick({
    menuPath: ["File","Import","Audio..."],
});
//Define Import Audio Window
const openWin = sf.ui.proTools.windows.whoseTitle.is('Open').first;
//Wait for 'Open' Window
openWin.elementWaitFor({waitType: "Appear"});
//Open 'Go' Sheet
sf.keyboard.type({ text: '/' });
//Wait for 'Go' Sheet Window to Appear
openWin.sheets.first.elementWaitFor({waitType: "Appear"});
//Set Destination
openWin.sheets.first.textFields.first.elementSetTextAreaValue({
    value: `${importDirectory}`,
});
//Press Return
sf.keyboard.press({
    keys: "return",
});
//Wait for 'Go' Sheet Window to Disappear
openWin.sheets.first.elementWaitFor({waitType: "Disappear"});
//Select All
sf.keyboard.press({
    keys: "cmd+a",
});
//Click "Copy"
openWin.buttons.whoseTitle.is("Copy ->").first.elementClick();
//Click "Open"
openWin.buttons.whoseTitle.is('Open').first.elementClick();
//Reference Folder Window
const folderWin = sf.ui.proTools.windows.invalidate().getByTitle("Choose a destination folder");
//Wait for Folder Window to Appear
folderWin.elementWaitFor({waitType: "Appear"});
//Click Open
folderWin.buttons.whoseTitle.is('Open').first.elementClick();
//Reference to Audio Import Options Window
const aIOWin = sf.ui.proTools.windows.whoseTitle.is("Audio Import Options").first
//Wait for 'Go' Sheet Window to Appear
aIOWin.elementWaitFor({waitType: "Appear"});
//Click "OK" to New Track
aIOWin.buttons.whoseTitle.is("OK").first.elementClick();
//Wait
sf.ui.proTools.waitForNoModals();
