FileNotFoundError for event generation

Hi there, I am using MadMiner v0.9.6. CUrrently, I am getting an error to generate events in MadGraph through MadMiner. Here is my code and the error:

miner.run(
    sample_benchmark='sm',
    mg_directory=mg_dir,
    mg_process_directory="./tth_event",
    proc_card_file='../cards/proc_card_mg5.dat',
    param_card_template_file='../cards/param_card.dat',
)

FileNotFoundError: [Errno 2] No such file or directory: './tth_event/None'

Note that these are the files created in the tth_event directory:

tth_event
└── madminer
    ├── cards
    │   ├── param_card_0.dat
    │   └── reweight_card_0.dat
    └── scripts

I suspect that the auto-naming of the files 'param_card_0' and 'reweight_card_0' in tth_event could be a problem. (I have never generated events in MadMiner environment before, I always had some issues. This is the latest one.) Any help on this will be highly appreciated. Thanks!
