Cannot unmarshal hex number with leading zero digits into Go struct field

[sfurionix]

Example response from Eth: Client RPC error response [uri] / [method] eth_estimateGas [error code] -32602 [error message] invalid argument 0: json: cannot unmarshal hex number with leading zero digits into Go struct field CallArgs.value of type *hexutil.Big
Method EthQ::hexValUnpadded() must return a string without leading zeros. For example, 0.2 ether (200000000000000000 wei) should be converted to 0x2c68af0bb140000 instead of 0x02c68af0bb140000.
