Our Docker image uses Chromium v57, which is not supported by chromedriver versions after 2.38. See https://bugs.chromium.org/p/chromedriver/issues/detail?id=2445 The reason that the version of chromium is so old is that our base image ruby:2.3.6 (the standard image for Ruby 2.3.6 on DockerHub) is built on Debian 8 (jessie), which was made obsolete over a year ago. The best solution is probably to upgrade the application to Ruby 2.3.7 (if not later), so we can use the official ruby:2.3.7 image, which is kept up-to-date (it has Chromium 68). Alternatively, we could try to install Chromium from a more up-to-date repository, but this is probably not worth the trouble.
