## Problem
I am migrating from Trello to Linear using `@linear/import`. I exported my data from Trello and ran the importer, but it crashes with `TypeError: data.checklists is not iterable`. Checklists and comments both fail to import. Did I export the data wrong, or is this a bug in the importer?
## Verified fix
You exported the wrong thing. The importer expects the Trello JSON you get from exporting a single board (via the board menu). If you export the entire workspace instead, the JSON schema for checklists differs and the importer crashes with `TypeError: data.checklists is not iterable`. The reporter confirmed that re-exporting the board individually made the import work, including checklists and comments. So do not use the workspace-level export; export each board separately and import those files.
