Matthias Pohl commented on FLINK-36295:
---------------------------------------
The issue is that the job was cancelled while the 1st checkpoint was created:

{code}
This triggers the job cancellation without any restart which is why we do not
see any checkpoint being returned as part of the {{CheckpointStatsSnapshot}}.
It's yet unclear why the job was cancelled.
