        The return value for era can either be `mortalEra`, or `immortalEra` and is represented as an enum in substrate. `immortalEra` meaning
        the transaction is valid forever. `mortalEra` consists of a tuple containing a period and phase.
        ex: `"{"mortalEra": ["64", "11"]}"`. The Period is the period of validity from the block hash found in the signing material.
        The Phase is the period that this transaction's lifetime begins (and, importantly,
        implies which block hash is included in the signature material).
