[BUG] Unable to send transaction on UTXO chains

[CopsLikeDonuts]

When I'm trying to send transaction on LTC/DASH chains extension is just infinite loads and there is no response from it. I checked extension console and there is an error attached on a screenshot.

params that I send are

{ "asset": { "chain": "LTC", "symbol": "LTC", "ticker": "LTC" }, "from": "ltc1qwxl602nuqv9juh83q9n9u6rpcngur52mq48np9", "to": "ltc1qwxl602nuqv9juh83q9n9u6rpcngur52mq48np9", "amount": { "amount": "300000", "decimals": 8 } }
