unbuild doesn't export type declarations by default, so I added declaration: true, When I add it and try to execute unbuild, I get an error。

it's my config

import { defineBuildConfig } from 'unbuild'
export default defineBuildConfig({
  entries: ['src/index'],
  clean: true,
  failOnWarn: false,
  declaration: true,
  rollup: {
    inlineDependencies: true,
    esbuild: {
      minify: true
    }
  },
  alias: {
  },
  hooks: {
    'rollup:options'(ctx, options) {
      if (!options.plugins) {
        options.plugins = []
      }
    }
  }
})

my node version 16.18.0， unbuild version is 0.9.4

It's difficult to understand the issue without knowing the source code, at least the line that is causing the error. Anyway, if you remove the rollup configuration object, does the error persist?

[dwightjack]

Oh, wait! Maybe this issue is the same as #112. If so it is probably an issue using esbuild minify and declaration: true together.

I have added declaration to the min+ sourcemap fixture (7dcda3f) and seems to be working fine on latest main (upcoming release)

Please let me know if you still had issues to reopen and track.
