How to get more information, to build reproducable repo?

[alexbjorlig]

I'm trying to test out rolldown in my Sveltekit project, but it fails with:

rolldown-vite v7.1.8 building SSR bundle for production...

thread '<unnamed>' panicked at crates/rolldown_binding/src/utils/normalize_binding_options.rs:472:37:

fatal runtime error: failed to initiate panic, error 5, aborting

It's a rather large project, with a lot of settings. Is there a way to get more information about what this error could be related to - so I can go around building a reproduction?

The issue is regarding the native alias plugin which only accepts strings, but a boolean is passed to it instead.
Your Vite config might contain the alias directly or a plugin is setting it.

Still, a panic shouldn't happen. Similar to rolldown/rolldown#5817.

Raised in rolldown/rolldown#6122

Thanks @TheAlexLichter 👍

Turns out I had this in my vite.config

resolve: {
        alias: {
            prettier: 'prettier/standalone',
            fsevents: false, // Exclude fsevents from the build to avoid issues on non-macOS systems
        },
    },

After removing this, this specific error is not there anymore. However, now I get this error:

Again, running with RUST_BACKTRACE=full. What could this be related to?

[TheAlexLichter]

rolldown/rolldown#6122 Alias should support false too I guess. 🤔 But that's maybe not implemented yet.

The new error message looks like an issue with SvelteKit directly (the compile plugin). Might be worth to debug that further and log which function fails!

[alexbjorlig]

Thanks for the quick answer, is that something I can do or?

[TheAlexLichter]

@alexbjorlig absolutely!

The last stacktrace part tells you which functions it went through.

If you could set debuggers there and figure out "which part/function is failing" that'd be ideal.
