EncodableReturnType is not implemented for Nested Structs

[Ifechukwudaniel]

sol! {
#[derive(Debug, Copy)]
struct Data {
uint id;
uint value;
}

#[derive(Debug, Copy)]
struct DataOption {
bytes32 id;
Data data;
Data value;
}
}
#[public]
impl Contract {
pub fn query_price_feed(&self, id: FixedBytes<32>) -> Result<DataOption, Vec> {}
}

^^^^^^ the trait EncodableReturnType is not implemented for Result<Vec<DataOption>, Vec<u8>>

Is there a way to return DataOption
