@pi0 I suppose "Only merge plain objects (#​111)" is considered a bugfix but maybe you are interested in knowing that it breaks testing here.

The code is roughly:

const config = await import(`${dir}/fixture/${fixture ? fixture + '/' : ''}nuxt.config.cjs`)

const result = defu(override, config)

and those are logged objects:

  override: {
    sentry: {
      dsn: 'http://acacaeaccacacacabcaacdacdacadaca@localhost:58160/000001'
    }
  },
  config: [Object: null prototype] [Module] {
    rootDir: [Getter],
    telemetry: [Getter],
    dev: [Getter],
    render: [Getter],
    modules: [Getter],
    sentry: [Getter],
    publicRuntimeConfig: [Getter],
    default: {
      rootDir: '/usr/local/workspace/nuxt/sentry-module/test/fixture/lazy',
      telemetry: false,
      dev: false,
      render: [Object],
      modules: [Array],
      sentry: [Object],
      publicRuntimeConfig: [Object]
    }
  },
  result: {
    sentry: {
      dsn: 'http://acacaeaccacacacabcaacdacdacadaca@localhost:58160/000001'
    }
  }

So the object returned from async import is strangely not a POD and it fails. Not sure if that's normal for async import or it's because of running within jest but I guess it's an interesting case where this bug fix is a breaking change.

I'm adding a workaround for this but I wonder whether this apparent fix should be adjusted to work in this case...

I'm gonna do:

  // Returned object has "Module" type which defu ignores because it's not plain object.
  // Copy properties to the new object so that the object is not ignored.
  const config = Object.assign({}, await import(`${dir}/fixture/${fixture ? fixture + '/' : ''}nuxt.config.cjs`))
