  - models such as RequestQueueMetadata specify camelCase aliases
  • this suggests that we originally intended to maintain the same on-disk format as crawlee-js
  • FileSystemStorageClient calls model_dump without by_alias=True - that means that the files will be snake_case
• I found this while working on the Rust file system storage client
• @vdusek perhaps you remember if this was intentional?

This will be a breaking change.
