@letItCurl this happens when you render a view from a background job. In views that are rendered during an HTTP request rails has access to the current request and can infer the host for links and forms from there. But in a background job there's no current request and rails uses a default placeholder host.

You can fix this defining a default host in your application controller.

class ApplicationController < ActionController::Base
  def default_url_options
    { host: Rails.application.config.default_host }.compact_blank
  end
end

Then set config.default_host in your environments.

Are these configurations documented in the README.md or on a class somewhere that would be surfaced in the RubyDoc site?

[afcapel]

@seanpdoyle not that I'm aware of. This is really a Rails issue, it happens when rendering from a background job, even without any Turbo involved. There's an issue open to make this configuration simpler and more explicit.

rails/rails#39566
