Django Upload Folder is always Empty (This field is required issue)

Question

I would like to upload a folder to my application but on the server side the request.FILES collection is always empty.

Also form.is_valid evaluates to false

The solution for this problem seems to be to add enctype="multipart/form-data" but I have already added it an it doesn't work. As described here SO TOPIC ABOUT THIS

Inside the browser I also get "This field is required" after pressing submit and yes I have choosen a directory.

Here my relevant code

model.py

# Create your models here.
class Datasets(models.Model):

    dataset_name = models.CharField(max_length=100, blank=True, null=True)
    description = models.CharField(max_length=1000, blank=True, null=True)
    share_with = models.ManyToManyField(User)
    uploaded_by = models.CharField(max_length=1000, blank=True, null=True)
    upvotes = models.IntegerField(null=False, default=0)
    downvotes = models.IntegerField(null=False, default=0)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    datafiles = models.FileField(blank=True, null=True)

form.py

class UploadDatasetForm(forms.Form):

    dataset_name = forms.CharField(
        max_length=1000,
        widget=forms.TextInput(attrs={'class': 'form-control'}))
    description = forms.CharField(
        max_length=1000,
        widget=forms.TextInput(attrs={'class': 'form-control'}))
    share_with = forms.MultipleChoiceField(
        choices=tuple(UserProfile.objects.values_list('id', 'full_name')),
        widget=forms.CheckboxSelectMultiple,
    )
    datafiles = forms.FileField(widget=forms.ClearableFileInput(
        attrs={
            'multiple': True,
            'webkitdirectory': True,
            'directory': True,
        }))

the template

{% block content %}
<h2>Register Here</h2>
  <form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Register</button>
  </form>

view.py

@login_required
def upload_dataset(request):
    print(request.user)
    form = UploadDatasetForm()
    if request.method == "POST":
        print('Receiving a post request')
        form = UploadDatasetForm(request.POST, request.FILES)
        print(request.FILES)

        if form.is_valid():
            print("The form is valid")
            print(form.cleaned_data)

            dataset_name = form.cleaned_data['dataset_name']
            description = form.cleaned_data['description']
            datafiles = form.cleaned_data['datafiles']
            share_with = form.cleaned_data['share_with']
            users_to_share_with = set()

            print(datafiles)

            instance = Datasets.objects.create(
                uploaded_by=request.user,
                dataset_name=dataset_name,
                description=description,
                datafiles = datafiles,
                upvotes=0,
                downvotes=0,
            )

            for i in share_with:
                instance.share_with.add(i)

            return redirect("public:data")
            print("The Dataset has been uploaded")

    context = {"form": form}
    return render(request, "upload_dataset.html", context)
    {% endblock %}

I receive the message Receiving a post request but it will not go inside the form.is_valid

The output after pressing the submit button is
