I have been attempting to set up functional testing using Intern 4 with a headless Chrome browser. I have installed selenium-server-standalone on my Mac terminal and believe everything is configured correctly. However, when I try to run the test, I encounter the following error:
Running "exec:test_functional" (exec) task
Listening on localhost:9000 (ws 9001)
Tunnel started
BUG: suiteEnd was received for invalid session

I am using the latest versions of Node, npm, and Intern.
Any assistance in resolving this issue would be greatly appreciated.
EDIT:
app.ts
// tests/functional/app.ts
const { suite, before, test } = intern.getPlugin("interface.tdd");
const { expect, assert } = intern.getPlugin("chai");
suite("app", () => {
before(({ remote }) => {
return remote
.get("src/app.html")
.setFindTimeout(5000)
.findDisplayedByCssSelector("body");
});
let windowHandles: any;
test("testing", ({ remote }) => {
return remote
// Click login button
.findByClassName('hero-cta')
.click()
.end()
// Switch to login window
.getAllWindowHandles()
.then(function(handles: string[]){
windowHandles = handles;
assert.isArray(windowHandles);
return remote.switchToWindow(windowHandles[1]);
})
// Input user credentials and submit
.findById('user_username')
.type('username')
.end()
.findById('user_password')
.type('password')
.findAllByCssSelector('button')
.click()
.end()
//Switch to app
.getAllWindowHandles()
.then(function(handles: string[]){
assert.isArray(handles);
return remote.switchToWindow(windowHandles[0]);
})
.find('css selector','span')
