Problem with LigandMPNN reading RFD3 output

Hello. I ran RFD3 renaming my ligand as suggested in a previous issue [https://github.com/RosettaCommons/foundry/issues/97](url), but when I try to use the resulting structures for LigandMPNN, I get this error:
    The following CCD codes were not found in Biotite's built-in CCD: {np.str_('L:G')}
Is there a way to solve this?
