Hello @cplanas! The following code example is missing a comma between :mem_cache_store and the {:

config.​identity_cache_store​ = ​:mem_cache_store​ {​   ​
  expires_in: ​6.​hours​.​to_i​,​   
  ​failover: ​​false​,​
}

should be

config.​identity_cache_store​ = ​:mem_cache_store​, {​   ​
  expires_in: ​6.​hours​.​to_i​,​   
  ​failover: ​​false​,​
}
