Summary0011772: Automatic migration writes a cryptic error message
DescriptionWhen doing the automatic migration for the standard app, I receive a message to update de data base.
I click OK and executes it.
Then I get the following error message:
{
  "code": 7034,
  "hint": "Error (WALLET_DB_UNAVAILABLE)",
  "message": null,
  "when": {
    "t_ms": 1788163179637
  },
  "innerError": {
    "code": 7001,
    "when": {
      "t_ms": 1788163179637
    },
    "hint": "unexpected exception (message: conversion verification failed: denominationFamilies differs between source and destination (103:2e1eb578972b0e1df9523f81754b711e2d2968ba1184423587358ecc188f54aa versus 103:26506344b3fb45c3930147ee35ec356e6237dcde38388837dd480265dc333f75))",
    "stack": " at convertWalletDb (<compiled_js>:44598:20)\n"
  }
}

The wallet DB included some legacy fields from very old versions that the migration didn't expect.

Migration should be fixed in wallet-core v1.6.41.
