In https://docs.python.org/3/library/asyncio-task.html#task, there is a note about a warning being logged if a pending task is destroyed.  The section does not explain or link to an explanation of how a task might get destroyed.  Nor does it define pending, but that seems reasonably clear from context (ie: the future has not completed).

The example linked to does not show how the pending task got destroyed, it only shows an example of the resulting logging, with not enough information to really understand what the final line of the error message is reporting (is kill_me an asyncio API, or the name of the task, or the future it is wrapping?)
