Environment

node: v20.9.0 pnpm: 8.15.4 "typescript": "^5.4.2",

Reproduction

github repo pnpm i pnpm build It will throw error.

Describe the bug

See build.config.ts in the mini-repo above. The option of defineBuildConfig will throw error:

export default defineBuildConfig({
  // ...
  hooks: {
    'rollup:options': (_, options) => {
      options.plugins = [
        options.plugins,
      ]
    },
  },
})

Cannot read properties of undefined (reading '_options')

// Locate this line of code
shebangPlugin2._options.preserve = false;

But Vitejs use code like it, refer to Vite Repo And the type also looks it should work:

type InputPluginOption = MaybePromise<Plugin | NullValue | false | InputPluginOption[]>

Additional context

No response
