Couldn't load XPCOM

[inactdev]

Thanks for the buildpack 😃

I'm getting this error when trying to start a new instance of Selenium Webdriver:

XPCOMGlueLoad error for file /app/vendor/firefox/libxul.so:
libXt.so.6: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Any ideas ? I've set all the environment variables in the README. Here's my configuration :

Selenium::WebDriver::Firefox::Binary.path = ENV['FIREFOX_BIN']
Selenium::WebDriver::Firefox.driver_path = ENV['GECKODRIVER_PATH']
Selenium::WebDriver.logger.level = :debug

Thanks !

Thank you for using heroku-integrated-firefox-geckodriver. Preliminary examination of your issue is underway.

The reported error is not confined to this build pack; evident from the fact that you were able to deploy the application.

Hence I'm not sure if I can help you here.

An XPCOM related error usually roots back to improper usage of firefox libraries.

A runtime error while creating the web driver instance, suggests that the application code is probably creating a troubling subroutine of some sort. I can help you debug if you can share some logs and relevant application code snippets.

I am also experiencing this problem. No problems with Chrome. System.setProperty("webdriver.gecko.driver", System.getenv("FIREFOX_BIN")); WebDriver driver = new FirefoxDriver();
