When warp syncing a node we import a header of the parachain around the tip of the chain. This header is currently not imported as finalized block (should be fixed at some point as well), the parent headers are not yet present (still being synced) and thus, we run into a panic. Even if there is a case where a leaf could not be found in the database, this probably means that the db is broken and it will fail somewhere elese.
