Axum tutorial is broken

[dpasirst]

The axum tutorial seems wildly broken :-(

I did this

git clone https://github.com/kanidm/webauthn-rs.git
# optional (same problem with or without): git checkout v0.5.1
cd webauthn-rs/tutorial
make axum

I expected the following

to successfully build the tutorial AND for the tutorial to work (see "Any other comments")

What actually happened

cd server/axum && ./build_wasm.sh && cargo run
Error: `cargo metadata` exited with an error: error: failed to parse manifest at `/Users/dave/developer/rust/webauthn-rs/tutorial/wasm/Cargo.toml`

Caused by:
  error inheriting `serde_json` from workspace root manifest's `workspace.dependencies.serde_json`

Caused by:

Any other comments

The build is just the first problem. There are several other things broken with the tutorial code (note: these problems are with the tutorial code only, while the webauthn-rs/compat_tester/webauthn-rs-demo does seem to work (at least I am prompted to register a passkey).

After modifying webauthn-rs/tutorial/wasm/Cargo.toml and webauthn-rs/tutorial/server/axum/Cargo.toml to get the code to build. The server starts listening on port 8080 but the demo does not function.

• The assets/wasm/index.html file expects ./wasm.js and ./wasm_bg.wasm however, the files available are ./wasm_tutorial.js and ./wasm_tutorial_bg.wasm. After modifying the index.html to the new names, the start_register appears to work per the server logs but I'm never prompted to register a passkey. The browser (chrome) inspect console shows a list of unintelligible errors from the wasm code.
• Modifying the build feature for 'javascript' instead of 'wasm' is also a problem. Going to https://localhost:8080/ returns a 404 error because main.rs code has the following lines:

    #[cfg(feature = "javascript")]
    let app = Router::new()
        .merge(app)
        .nest_service("/assets", tower_http::services::ServeDir::new("assets/js"));
      ### ^^^^^^^^^^^^^^^^^^^^^^^^^########
     # "/assets" probably should be "/"

After making that change, then assets/index.html requires /assets/auth.js to be modified to /auth.js. But even then the tutorial itself fails to complete registration with seemingly start_register being called no prompt to register a passkey.

@dpasirst Edit the make file and change

axum: ## Build and run the axum server
axum:
	cd server/axum && ./build_wasm.sh && cargo run

to

axum: ## Build and run the axum server
axum:
	cd server/axum && cargo run

@Firstyear - that fixes the compiling of the tutorial (THANKS!), but not the tutorial itself. That is still broken per the comments in the Any other comments section.
