Test Case

Cardano.Wallet.DB.Sqlite, Sqlite State machine tests, Sequential

Failure / Counter-example

  1) Cardano.Wallet.DB.Sqlite, Sqlite State machine tests, Sequential
       uncaught exception: PersistException
       PersistMarshalError "Couldn't parse field `txMetaData` from table `tx_meta`. ConversionErrExpected \"[Aeson.String x]\" \"fromList [(\\\"hex\\\",Array [Number 0.0])]\""
       (after 1491 tests and 68 shrinks)

  2) Cardano.Wallet.DB.Sqlite, Sqlite State machine (RndState), Sequential state machine tests
       uncaught exception: PersistException
       PersistMarshalError "Couldn't parse field `txMetaData` from table `tx_meta`. ConversionErrExpected \"[Aeson.String x]\" \"fromList [(\\\"hex\\\",Array [Number 0.0])]\""

Resolution

• The current metadata to/from json conversions is broken. We've proposed an alternative that roundtrips for data coming from JSON. This is used in Temporarily use metadata revision branch of cardano-api #2131 which fixes conversions issues.
