Error message

call_saved_workflow could not access board '{board_id}' for image generator expansion

What it means

While expanding an image_generator (images_from_board) node in a called batch child workflow, InvokeAI tried to fetch the referenced board and the board_records.get(board_id) call raised. The underlying storage exception is chained ('from e'); the board may not exist, may be corrupted, or the store may be failing, and expansion cannot enumerate the board's images.

Solutions

1. Verify the board_id exists (e.g. list boards via the API) and update the workflow's image_generator node to a valid board id
2. Remove the board reference and supply images via a direct list on an image_batch node instead
3. Restore the missing board or repair the board records database if the store is failing
4. Call without a user_id context only if board access control is not required, or run as an admin user

Example fix

// after
{ "type": "image_generator_images_from_board", "board_id": "1a2b3c4d-..." }  // existing board id

When it happens

Trigger: Calling a saved workflow whose image_generator node references a board_id that does not exist in the board records store (deleted board, board from another install/database, or a transient DB failure), when the caller has a user_id and the service layer propagates the error.

Common situations: Sharing workflows between machines/databases where board ids don't resolve; deleting a board that a saved workflow still references; SQLite/database corruption or read failures; running with multi-user auth where boards live in another account's records.
