stack build throwing error for type: 'Money', No instance for (Eq Money)

error log

/Users/streamerd/Developer/hs/haskellAtWork/projectz/Project.hs:28:21: error:
    • No instance for (Eq Money)
        arising from the first field of ‘Sale’ (type ‘Money’)
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Eq Transaction)
