I have an entity declaration in persistent as follows:

share [mkPersist sqlSettings { mpsGenerateLenses = True, mpsPrefixFields = False }, mkMigrate "migrateAll"] [persistLowerCase|
    Account
        accountNo           Text
        accountType         AccountType  
        accountHolderName   Text  
        accountOpenDate     UTCTime default=CURRENT_TIME
        accountCloseDate    UTCTime Maybe default=NULL
        currentBalance      MoneyUSD
        rateOfInterest      Double
        Primary             accountNo
        deriving Show
|]

I am getting this compilation error ..

• No instance for (Generic (Key Account))
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (aeson-1.4.6.0:Data.Aeson.Types.ToJSON.ToJSON
                                        (Key Account))
