Loader issue using NuxtJS

When trying to import a contract factory, the following generated line throws an error:

```
...
export * as factories from "./factories";
...
```

I think it may be related to exporting a directory instead of a file, but I can't find a fix.
If I remove this line, it works, but generated code shouldn't be edited.

The displayed error is the following: `You may need an additional loader to handle the result of these loaders.`
