Since 2.4.4, Percy has had protection to stop you accidentally trying to turn it on without specifying a project.
However, the protection only kicks in if you're configuring Percy using the PERCY_TOKEN environment variable, whereas wider Percy documentation (the percy-client gem) gives an alternative way to configure, using the Percy.config.access_token accessor.
percy-capybara should work identically regardless of how it was configured.
