`?` operator has incompatible types with try_map and parse_with

[Emilgardis]

this works in 0.11

#[derive(BinRead,)]
#[br(little)]
pub struct Meta {
    /// ID
    pub id: [u8; 6],
    /// Serial number
    #[br(pad_before = 1, parse_with = binrw::helpers::until_eof, try_map = String::from_utf8)]
    pub serial_number: String,
}

it seems to no longer work in 0.13, giving me
