Selenium on heroku DevToolsActivePort file doesn't exist - node.js

Question

So, I'm trying to deploy a node, selenium app to heroku.
This is how my code looks
let options = new Options();
options.setChromeBinaryPath(process.env.GOOGLE_CHROME_BIN);
options.addArguments("--headless");
options.addArguments("--start-maximized");
options.addArguments("--headless");
options.addArguments("--disable-dev-usage");
options.addArguments("--window-size=1920,1080");
options.addArguments("--ignore-certificate-errors");
options.addArguments("--allow-running-insecure-content");
options.setUserPreferences({"prefs":{"useAutomationExtension": false}});
let serviceBuilder = new ServiceBuilder();
console.log("initialized serice builder");
let driver = new Builder(process.env.CHROME_EXECUTABLE_PATH)
.forBrowser(Browser.CHROME)
.setChromeOptions(options)
.setChromeService(serviceBuilder)
.build();
This throws an error on the heroku logs like so

Nothing seems to fix the issue, I've added the required buildpacks, and have also checked all the versions. Also note that this code runs perfectly fine on my local machine. I saw a similar question where the user manually added the DevToolsActivePort file, but that doesn't seem to be possible as I can't ssh into the heroku server.
Thanks in advance.

You will need to pass in a flag to disable Chrome Devtools Sandbox, so it will no longer look for DevToolsActivePort. It is also recommended to disable-gpu with a headless webdriver:
options.addArguments("--headless");
options.addArguments("--no-sandbox");
options.addArguments("--disable-gpu");
