how to correctly to resume work

[tusik]

my config is

cache:
  type: file # one of [blob, cosmosdb, file]
  base_dir: "cache"

i'm index 100M files, embedding api have some problem when extract graph is finished, i'm tring to resume work

graphrag index --root . --resume [timestamp find in index-eninge.log]

# index-engine.log
09:14:04,701 graphrag.cli.index INFO Starting pipeline run for: 20250110-091404, dry_run=False
# why hide the timestamp, it just only write in index-eninge.log now, no screen output, no named cache folder

And just re-extract graph now, is something i did wrong?
So resume not work just waste my 200M tokens from last work?
