The currency code is invalid and does not follow ISO 4217.
UNSUPPORTED_CURRENCY_CODE
The currency code is not supported.
CURRENCY_CODE_ALREADY_EXISTS
The currency code already exists. When creating an exchange rate, its currency should not be
associated with any existing exchange rate. When creating a list of exchange rates, there
should not be two exchange rates associated with same currency.
INVALID_EXCHANGE_RATE
The exchange rate value is invalid. When the ExchangeRate.refreshRate is
ExchangeRateRefreshRate.FIXED, the ExchangeRate.exchangeRate should be larger
than 0. Otherwise it is invalid.
EXCHANGE_RATE_NOT_FOUND
The exchange rate value is not found. When the ExchangeRate.refreshRate is
ExchangeRateRefreshRate.DAILY or ExchangeRateRefreshRate.MONTHLY, the
ExchangeRate.exchangeRate should be assigned by Google. It is not found if Google
cannot find such an exchange rate.
UNKNOWN
The value returned if the actual value is not exposed by the requested API version.
