Trying to generate resources with wn:resources error

[Duxez]

Whenever I try to generate resources with wn:resources I'm getting this error:
Illegal string offset 'name'
I've tried searching on Google to see if I could find a solution that way, but I sadly couldn't find one.

The error comes from this file: ResourcesCommand.php line 95

Which says:

foreach($i['fields'] as $name => $value) {
            $value['name'] = $name;
            $fields[] = $this->serializeField($value);
}

But I do not understand what's wrong there.
