Describe the Bug
@vitejs/plugin-rsc requires building certain environments multiple times. The build error is found in vitejs/vite-plugin-react#851. Simplified version would look like the minimal reproduction above:
{
builder: {
async buildApp(builder) {
await builder.build(builder.environments.ssr!);
await builder.build(builder.environments.ssr!);
}
}
}This logic seems to have a problem with @cloudflare/vite-plugin since v1.13.0 and the error look like this:
$ pnpm build

error during build:
[vite]: Rollup failed to resolve import "virtual:cloudflare/user-entry" from "virtual:cloudflare/worker-entry".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`

ELIFECYCLE Command failed with exit code 1.From what I debugged so far, workerConfig.main during the 2nd build became different from the wrangler.jsonc's main field
workers-sdk/packages/vite-plugin-cloudflare/src/index.ts
Lines 220 to 222 in 597e07a
During the first build, console.log({ source, main: workerConfig.main }) logs
{
source: 'virtual:cloudflare/user-entry',
main: '/home/hiroshi/code/personal/reproductions/vite-rsc-851-cloudflare-entry-virtual/worker/index.js'
}
but during the 2nd build, it becomes
{ source: 'virtual:cloudflare/user-entry', main: 'index.js' }
