browserless-playwrite.rb

require "playwright"
uri = "wss://chrome.browserless.io/playwright?token=#{browserless_api_key}"
Playwright.connect_to_playwright_server(uri) do |playwright|
  playwright.chromium.launch do |browser|
    page = browser.new_page
    page.goto("https://github.com/YusukeIwaki")
    page.screenshot(path: "./YusukeIwaki.png")
  end
end

My package.json contains "playwright": "1.27.1", and Gemfile contains gem "playwright-ruby-client", "~> 1.31"

The error I get looks like:

Perhaps there's an issue related to playwright versions. The playwright rubygem seems to want playwright verson 1.31.1

$ bundle exec ruby -e "require 'playwright'; puts Playwright::COMPATIBLE_PLAYWRIGHT_VERSION.strip"
1.31.1

But looking at the gem I'm unsure where this version number is used; or how it might affect the connection to browserless.

The playwright version could be the issue, make sure you install a supported playwright version, since playwright is tightly version coupled -> https://www.browserless.io/docs/versions
