In addition to the above error, a different error now also appears on older DAGs that newly include a mapped task. The mapped tasks are created in a sense, but their status remains on "no status". When clicking the "Run" button, the following error appears: ``` Could not queue task instance for execution, task instance is missing ``` I'm also observing high metadata database CPU and the scheduler slows to a crawl, such that other tasks take several minutes to be scheduled. I'm guessing the scheduler doesn't quite know what to make of these (several thousand) broken tasks and keeps looping over them. -- This is an automated message from the Apache Git Service.
