Hello, we would like for reference tasks to grab the latest version. The version parameter in the reference_task decorator is required, for our CICD we do not want to manually set this and our workflows and tasks are preregistered. I am able to grab the latest task version using FlyteRemote.

Can you use the

{{ registration.version }}

macro as described here - https://docs.flyte.org/projects/cookbook/en/v0.3.66/auto/core/flyte_basics/reference_task.html#reference-task

a complete example would be more helpful. What are the prerequisites for the macro to work? The task and workflow are registered using pyflyte register,I get.

Request rejected by the API, due to Invalid input.
RPC Failed, with Status: StatusCode.INVALID_ARGUMENT

@boundless-lifeguard-61788 looks like that macro is supported by

flytectl register

only at the time

The intention is the CICD to grab the latest version of reference tasks and workflows in a workflow. If I try

flytectl register

on my workflow which contains a reference task, it only works if I pass it the version which defeats what I am trying to do.

pyflyte --pkgs test package -f

flytectl register files --archive flyte-package.tgz --version "ADKDdgdgTEfg" -p test -d development

What would be the correct way for a CICD to fetch the latest task for a reference task

@reference_task(
    project="test",
    domain="development",
    name="simple.print_date",
    version="{{ registration.version }}",
)
def print_date() -> str:   
    ...



@workflow
def test()-> str:
    return print_date()

The errors if I leave --version out

Error: rpc error: code = InvalidArgument desc = missing version
{"json":{},"level":"error","msg":"rpc error: code = InvalidArgument desc = missing version"

and if I give it a new version

version:\"1\"] with err missing entity of type TASK with identifier project:\"test\"  domain:\"development\"  name:\"simple.print_date\"  version:\"1\""
