hledger-api.hs:220:10: error:
    • Cannot derive Generic-based Swagger Schema for Price
      Price is a mixed sum type (has both unit and non-unit constructors).
      Swagger does not have a good representation for these types.
      Use genericDeclareNamedSchemaUnrestricted if you want to derive schema
      that matches aeson's Generic-based toJSON,
      but that's not supported by some Swagger tools.
    • In the expression:
        Data.Swagger.Internal.Schema.$dmdeclareNamedSchema @Price
      In an equation for ‘declareNamedSchema’:
          declareNamedSchema
            = Data.Swagger.Internal.Schema.$dmdeclareNamedSchema @Price
      In the instance declaration for ‘ToSchema Price’
