This field is required error

[isik-kaplan]

With this simple setup:

direct_s3_storage = S3OptimizedUploadStorage()

class FileUpload(models.Model):
    file = models.FileField(storage=direct_s3_storage)
    
class CsvUploadForm(ModelForm):
    class Meta:
        model = FileUpload
        fields = ["file"]

class FileUploadView(FormView):
    form_class = FileUploadForm
    template_name = "upload.html"

<form method="post" enctype="multipart/form-data">    
    {% csrf_token %}
    {{ form }}
</form>
{{ form.media.js }}

I keep getting File: This field is required.

When I add {{ form.media.js }} request.FILES is empty, and "file" in request.POST, when I remove the {{ form.media.js }} request.FILES has "file" and "file" not in request.POST

I have the app and the middleware.

I've tried to figure it out myself but couldn't. I feel like I'm missing something, but I'm not entire sure what. Should I initiate my form differently?
