An error in GALigandDock: ERROR: error! pharmacophore docking requires reference_pool to be as 'INPUT'!

I'm encountering an issue while running the code in 08.02-Ligand-Docking-pyrosetta.distributed.ipynb. An error occurs at the line '%time results = list(xml_obj(pose_obj))':

RuntimeError Traceback (most recent call last)

ERROR: error! pharmacophore docking requires reference_pool to be as 'INPUT'!

I am wondering if this error could be related to the PyRosetta version I am using. Alternatively, is there a way to provide a reference_pool to GALigandDock to resolve this issue? Any guidance or suggestions would be greatly appreciated.

Thank you!

Start by reproducing the failure in 08.02-Ligand-Docking-pyrosetta.distributed.ipynb at the %time results = list(xml_obj(pose_obj)) line, then inspect the GALigandDock configuration associated with the traceback. Determine whether the notebook supplies the required reference_pool setting or whether the documented PyRosetta version is compatible; done means the notebook runs without this error or clearly documents the required setup.
