There was a problem hiding this comment.
LGTM.
Probably a todo or something could be good not to forget to revert this to the :doc: idiom once the page is published.

What
#75405 added
task-sdk/docs/task-handler.rstand linked to it from the yaml Dags guide with:doc:task-sdk:task-handler``. That page has not been published yet hence CI fails.Current behaviour
When a PR builds only the
apache-airflowdocs, sphinx checks the link against the publishedtask-sdkdocs. The page is not there yet, so the docs build fails with:yaml-dags.rst:426: WARNING: unknown document: 'task-sdk:task-handler'Any airflow-core PR that builds docs hits this (for example #76376). #75405 passed because it changed both packages, so CI built both doc sets together.
Proposed change
Replace the
:doc:link with a plain URL to the task SDK task handler page.public-airflow-interface.rstalready links to the Task SDK this way.What's next
The URL returns a 404 until the next
task-sdkrelease publishes the page. After that, it can go back to:doc:task-sdk:task-handler``.{pr_number}.significant.rst, in airflow-core/newsfragments. You can add this file in a follow-up commit after the PR is created so you know the PR number.
