It seems this started to happen in rolldown-vite 7.1.9.
7.1.8 errors with [plugin photon:resolve-server] Error: Errored while load "C:/path/to/solid-hop-rolldown/src/server/server.ts" in `this.load`. Got The `PluginContext.load` only work at `resolveId/load/transform/moduleParsed` hooks. If you using it at resolveId hook, please make sure it could not load the entry module...

7.1.8 + "rolldown": "https://pkg.pr.new/rolldown@cf4ad6a" doesn't hang and 7.1.8 + "rolldown": "https://pkg.pr.new/rolldown@a9c1d9b" hangs. It's caused by changes between rolldown/rolldown@cf4ad6a...a9c1d9b. Specifically by rolldown/rolldown#6098 which moved self.plugin_driver.set_context_load_modules_tx(Some(module_loader.tx.clone())).await; before self.resolve_user_defined_entries(). This caused the hang to happen instead of the error.

@magne4000 @brillout While Rolldown can fix the hang and make the proper error happen easily, that won't unblock photon. The error message is unclear, but I understand that Rolldown does not support this.load when resolving the entry module (which is the case here). Is this necessary or can this be worked around on your side?

🤔 We’re using the load call to make sure server entry modules are only loaded after we’ve processed their entire dependency graph — that’s when we run static analysis to extract metadata.
While removing this call wouldn’t affect most use cases, it would break a few important ones.
There are likely alternative approaches we can explore, but I’ll need some time to investigate them properly.

@Blankeos could you try with the latest vike-photon version, this specific issue should now be resolved :)

[Blankeos]

Thanks for your hard work @magne4000 ! I have tried with vike-photon@0.1.20 (the latest as of now). But unfortunately still getting an error for SSR (but it's different now):

👇 Error

(Same errors for both not deleting and deleting the lock file)
