What version of flipper and Ruby are you using?

[jnunemaker]

What adapter are you using? The backtrace goes to a name method call for adapter. Are you using a homegrown one?

[KevinColemanInc]

@jnunemaker I think the issue was my gems were on different versions. This change in my gem file fixed it:

-gem 'flipper-ui'
-gem 'flipper-redis'
+gem 'flipper-ui', '~> 0.7.0.beta6'
+gem 'flipper-redis', '~> 0.7.0.beta6'
