prefect-openmetadata ModuleNotFoundError: metadata.generated.schema.api.services.ingestionPipelines.testServiceConnection

Hello Community.
I’m followed the steps listed here to install prefect-openmetadata

  1. Clone repo
  2. Make a venv
  3. pip install prefect-openmetadata
    (OpenMetadata server is already running)

Then I tried to run a simple flow from a guide here:
https://prefecthq.github.io/prefect-openmetadata/run_ingestion_flow/

  1. vim ./test.py (and put code here with set JWT and connection details for postgresql)
  2. run python ./test.py
    but it fails with
Traceback (most recent call last):
  File "prefect-openmetadata/./test.py", line 1, in <module>
    from prefect_openmetadata.flows import ingest_metadata
  File "prefect-openmetadata/prefect_openmetadata/flows.py", line 17, in <module>
    from metadata.generated.schema.api.services.ingestionPipelines.testServiceConnection import (  # noqa
ModuleNotFoundError: No module named 'metadata.generated.schema.api.services.ingestionPipelines.testServiceConnection'

Have no idea what I’m doing wrong here, becase the code fails on the 1st line during import

python --version
Python 3.9.17

pip freeze | grep openmeta
