`unkown throw type` error when composing multiple crate

[setoelkahfi]

I have a networking crate that depends on a crate_error_codes crate and uses cargo swift to generate the swift package of the networking crate. I got an error while generating Swift binding with the cargo swift package command:

unknown throw type: Some(External { module_path: "crate_error_codes", name: "ErrorResponse", namespace: "crate_error_codes", kind: DataClass, tagged: false })

But I ran the same command directly from the crate_error_codes itself without issue. Below is my data structure:

#[derive(Serialize, Deserialize, Debug, Error)]
#[tsync]
pub enum ErrorResponse {
    Unknown { error_code: ErrorCode, message: String },
    UserNotFound { error_code: ErrorCode, message: String },
    // continues ...
}

impl Error for ErrorResponse {}

impl Display for ErrorResponse {
    fn fmt(&self, f: &mut Formatter) -> fmt::Result {
        write!(f, "{:?}", self)
    }
}

#[repr(i32)]
#[derive(Serialize_repr, Deserialize_repr, Debug, EnumIter, Enum)]
#[tsync]
pub enum ErrorCode {
    Unknown = 0,
    //User-defined error codes start from 1000
    UserNotFound = 1000,
    // continues ....
