TypeError: Optimizer.converged() missing 1 required positional argument: 'gradient'

Hi,
i would like to evaluate the model as after generation of the structure:
mattergen-evaluate --structures_path=$RESULTS_PATH --relax=True --structure_matcher='disordered' --save_as="$RESULTS_PATH/metrics.json"

but got the following error:

(.venv) bpp@bpp:/mattergen-1.0.3/checkpoints/mattergen_base$ mattergen-evaluate --structures_path=$RESULTS_PATH --relax=True --structure_matcher='disordered' --save_as="$RESULTS_PATH/metrics.json"

Sorry for long posting outputfile. I could not able to find the source of error except one thing it is printed Atoms.calc = calc required as highlighted in bold.
Kindly help me in this regards.
Thanks.

Start with mattergen/scripts/evaluate.py, mattergen/evaluation/evaluate.py, and mattergen/evaluation/utils/relaxation.py, then inspect the installed mattersim/applications/batch_relax.py referenced by the trace. Compare the MatterGen relaxation calls with the installed MatterSim optimizer API and reproduce the command. Done means mattergen-evaluate completes with --relax=True and writes the requested metrics file without the calculator or converged errors.
