Input Path and nested ref doesn't work together properly (key error 'type')

[inkhey]

I tried to do something like this :

    @hapic.with_api_doc()
    @hapic.input_path(UserSchema(only=('user_id',)))
    def user_workspace(self, context, request: TracimRequest, hapic_data=None):
        pass

with :

class UserSchema(marshmallow.Schema):

    user_id = marshmallow.fields.Int(dump_only=True)
    email = marshmallow.fields.Email(required=True)
    display_name = marshmallow.fields.String()
    created = marshmallow.fields.DateTime(format='iso8601')
    is_active = marshmallow.fields.Bool()
    # TODO - G.M - 17-04-2018 - Restrict timezone values
    timezone = marshmallow.fields.String()
    # TODO - G.M - 17-04-2018 - check this, relative url allowed ?
    caldav_url = marshmallow.fields.Url(
        allow_none=True,
        relative=True,
        attribute='calendar_url'
    )
    avatar_url = marshmallow.fields.Url(allow_none=True)
    profile = marshmallow.fields.Nested(
        ProfileSchema,
        many=False,
    )

I get this error:

            # TODO: look schema2parameters ?
            jsonschema = schema2jsonschema(schema_class, spec=spec)
            for name, schema in jsonschema.get('properties', {}).items():
                method_operations.setdefault('parameters', []).append({
                    'in': 'path',
                    'name': name,
                    'required': name in jsonschema.get('required', []),
>                   'type': schema['type']
                })
E               KeyError: 'type'

../hapic/hapic/doc.py:97: KeyError

Look like input path and input query should be fixed in order to deal with nested ref.
