OpenAPI schema generation outputs incorrect type=float

[tomdtp]

I have raised this as an issue at django-rest-framework-gis already, but I am not sure if this might actually be an issue of DRF itself.

I am using the default way from the documentation to auto-generate an OpenAPI schema from my DRF endpoints:

    path(
        "openapi/",
        get_schema_view(
            title="My OpenAPI",
            description="My OpenAPI description",
            version="1.0.0",
        ),
        name="openapi-schema",
    )

However when analyzing the resulting output, it contains an incorrect type: float which is not supported in the OpenAPI spec. It should be type: number with format: float, right?

      - name: in_bbox
        ...
        schema:
          type: array
          items:
            type: float
        ...

I encountered this when using it with drf-gis and especially the BBOX filter there:

class ProtectedAreaGeoJSONViewSet(ListAPIView):
    schema = AutoSchema(operation_id_base="ProtectedAreaGeoJSON")

    queryset = Geodata.objects.all()
    bbox_filter_field = "geometry"
    filter_backends = (InBBoxFilter,)

Since DRF does the schema generation, I would assume this is an DRF issue?
