Receving 2 errors at whiscy and couldnt find answer

Hello, I have been receiving 2 errors in whiscy after running and I couldn’t find the meaning of these errors. The PDB file is available in the data bank. I assume the program could not find any residues considered active or passive. However, I couldn’t be sure and wanted to ask. If anyone with the same error could help me or explain these errors, I would be very happy. Thanks for the help in advance
