assets.preview is undefined

[sir-marc]

pendant to #640

i got the same error:

js: assets.preview.find(function (filename) {

                  ^

TypeError: Cannot read property 'find' of undefined

when i changed the code like the mentioned pull request in iframe.html.js on line 38 to:

if (!assets || !assets.preview) {
    return {
      js: 'static/preview.bundle.js',
    };
  }

I did not get an error message anymore, but the site is still not working. It does not create a static folder in which the manager.bundle.js should be.

@kadira/storybook v2.35.2

For me, this was a webpack.config.js issue. When I deleted the file to reverted back to storybook's default webpack config, build-storybook worked without the 'find' error.

This is not an option for me as I'm depending on vairous things from webpack such as loaders (not included in the base setup e.g. TS or Sass), Path mappings and Plugins.

The fix you did is a good one.
If I can get a sample repo, I could work on this more.

I think the problem is you node version doesn't have Array.prototype.find. Can you use a more modern version of node?

Please re-open if you are experiencing this issue with a modern version of node.

@ndelangen have the same error
and how with error TypeError: Cannot read property 'find' of undefined you got the idea of not modern version of node
Does undefined in your node have a .find method?

UPD: I've fixed the issue by disabling HotModuleReplacementPlugin in plugins

Does undefined in your node have a .find method?

Whoops, my bad; you're right.

Closing issue because it's v2. Please reopen if this is still an issue on the latest v3.
