Getting ValueError: malformed node or string on line 176 something in electrum v1 wallet (not sure about version though)

[sc0rp10n-py]

I ran the command for v2 first, it said

Unsupported Electrum2 wallet seed version 58

then I tried the Electrum v1 command
it gave me this error

i manually went to line 176 in my wallet file, on line 176, its just transaction array. (null parameter is passed in there)

like this

"tx_fees": {
        "txn-number": [
            null,
            false,
            1
        ],
        "txn-number": [
            null,
            false,
            1
        ],
        "txn-number": [
            null,
            false,
            3
        ],
        "txn-number": [
            null,
            false,
            2
        ]
    },

Does btcrecover.py work directly with the file? (As you are trying to use an extract script here)
