Generated artifacts in GitLab cannot be found

Question

I can find the generated successfully uploaded files in GitLab Artifacts, but I can't get them through the API or URL. It returns 404.

Below is my .gitlab-ci.yml.

stages:
  - quality

linting:
  image: python:3.11.4-slim
  stage: quality
  allow_failure: true

Only unit-test artifacts are available. The other two can only get files through this API.
