How others solved it
THEN Ensure that the workflow class has steps decorated with @step and that the utility functions `get_steps_from_class` and `get_steps_from_instance` are imported from `llama_index.core.workflow.utils` (not from a top-level package). Also verify that the `pyvis` library is installed.
from llama_index.core.workflow.utils import get_steps_from_class, get_steps_from_instance
