@BoD the intelli plugin fails on ApolloClientDirectiveStripperTest

     Actual [[query MyQuery { 
      person { 
        identity { 
          firstName @catch 
          lastName 
        } 
      } 
    } 
    ]] 
    Expected [[query MyQuery { 
      person { 
        identity { 
          firstName 
          lastName 
        } 
      } 
    } 
    ]] 

Do we need to add @catch to a list somewhere?
