Flyte enables production-grade orchestration for machine learning workflows and data processing created to accelerate local workflows to production.

Flyte

flytekit 1.13.13
flyteidl 1.13.5

For some reason I’m seeing this error
`AttributeError: 'Output' object has no attribute 'ref'`
when I try to run the following commands

```pyflyte --pkgs flyte.workflows package --image ${APP_NAME}:${IMAGE_VERSION} -f &&\
		flytectl register files --admin.endpoint $(FLYTE_ADMIN_HOST):443 -p $(FLYTE_PROJECT_NAME) -d $(FLYTE_PROJECT_DOMAIN) \
		    --version $(IMAGE_VERSION) --archive flyte-package.tgz"```
I think it’s a reference to <https://github.com/flyteorg/flytekit/blob/master/flytekit/core/promise.py#L815|this class>.. and in the <https://github.com/flyteorg/flytekit/blob/release-v1.6/flytekit/core/promise.py#L574|past> it did have a “ref” property. But not sure why it’s breaking now.

So the fix was returning a dataclass instead of a NamedTuple. It’s interesting that this issue did not get surfaced earlier since we’ve been on 1.13 for a while now
