error.code() and error handling

[npcnuno]

I can't get the error code from the backend, making error handling difficult on the client

I always get code = "Unknow error" when I try to get the error code from the backend

#[wasm_bindgen]
pub async fn refresh_token(refresh: String) -> Result<JsValue, JsValue> {
let mut client = AuthenticationClient::new(build_client());
let result = client
.refresh_token_admin(RefreshRequest {
refresh_token: refresh,
})
.await;

match result {
    Ok(response) => {
        let res = response.into_inner();
        Ok(JsValue::from_str(
            &serde_json::json!({
            "code" : "0",
            "description": res.auth_token.to_string()})
            .to_string(),
        ))
    }
    Err(error) => Err(JsValue::from_str(
        &serde_json::json!({
            "code": error.code().to_string(),
            "description": error.details(),
        })
        .to_string(),
    )),
}

}

Hi. The error code depends on the code that is returned by the server. Can you share some of your server code here?

[npcnuno]

let admin: Option<Admin> = match admin.unwrap().take(0) {
    Ok(a) => a,
    Err(_) => return Err(Status::internal("couldn't query db")),
};
if admin.is_none() {
    return Err(Status::internal("couldn't query db"));
}
let admin = admin.unwrap();
match create_jwt_auth(
    &decoded.uid,
    &admin.institution.id.to_string(),
    Previlege::from_str(&head.typ.unwrap()).unwrap(),
) {
    Ok(a) => Ok(Response::new(RefreshResponse { auth_token: a })),
    Err(_) => Err(Status::internal("couldn't create auth from refresh")),
}

}

Hi. This is already tested in the test cases:

tonic-web-wasm-client/test-suite/simple/client/tests/web.rs

Line 79 in c89a136

async fn test_error_response() {

I cannot suggest any meaningful solution for this unless I have a failing test full code which does not behave correctly.

Hi, I'm having the same issue. However, I only started encountering the issue once I swapped the traefik reverse proxy that handled grpc-web translation with the tonic_web crate.

I'm guessing this is an issue with tonic_web then. @npcnuno, is your server using that crate as well?

[npcnuno]

Yes @cyanic-selkie

I opened an issue on the tonic repository.

I have the same issue when I use tonic gprc server behind the nginx proxy
