<InMemoryUploadedFile: logo_Reverse.svg (image/svg+xml)> is not JSON serializable ... but other uploads work fine.

I have made file uploads before, and they work. However here i must have found a bug in graphene-file-upload.

{"errors":[{"message":"<InMemoryUploadedFile: Welnity_logo_Reverse.svg (image/svg+xml)> is not JSON serializable"}]}

@Thousif-S I would do following to resolve this issue:

1-Remove the VersatileImageFieldFile from your Mutation. Test it from the graphql view with arguments. Does it work now? 2 Change the VersatileImageFieldFile to ImageField. Test it from the graphql view with arguments. Does it work now?

Unfortunately graphene-file-upload hides the real error, so that makes you think that it’s related to graphene-file-upload, but in the end it was another error that i was not aware of.

In my case it was related to another field expecting different type of argument.

it means that you are not passing an expected input. like in my previous comment shows the actual error is

hidden by graphene-file-upload

in my instance i was missing the position

class JobInput(InputProto):
    anonymous = graphene.Boolean()
    title = graphene.String()
    attachment = Upload(required=False)
    new_categories = graphene.List(graphene.String)

    class Meta:
        model = Job
        fields = (
            'hidden',
            'description',
            'location',
            'organization',
            'title',
            'position',
            'application_link',
            )
        _generic = {'required': False}
        fields_kwargs = {
            'location': _generic,
            'hidden': _generic,
            }

...

class CreateJob(graphene.Mutation):
    status = graphene.Int()
    errors = generic.GenericScalar()

    class Arguments:
        details = JobInput(required=True)
