Gitlab ci issue with passing artifacts to Downstream pipeline with trigger and needs keywords

Question

I am working on a multi-pipeline project, and using trigger keyword to trigger a downstream pipeline, but I'm not able to pass artifacts created in the upstream project. I am using needs to get the artifact like so:

Downstream Pipeline block to get artifacts:

needs:
    - project: workspace/build
        job: build
        ref: master
        artifacts: true

Upstream Pipeline block to trigger:

build:
    stage: build
    artifacts:
    paths:
        - ./policies
    expire_in: 2h
    only:
    - master
    script:
    - echo 'Test'
    allow_failure: false

triggerUpstream:
    stage: deploy
    only:
    - master
    trigger:
    project: workspace/deploy

But I am getting the following error:

This job depends on other jobs with expired/erased artifacts:

I'm not sure what's wrong.

Looks like there is a problem sharing artifacts between pipelines as well as between projects. It is known bug and has been reported here:

https://gitlab.com/gitlab-org/gitlab/-/issues/228586

You can find a workaround there but since it needs to add access token to project it is not the best solution.
