Exporting and Loading Evaluation Traces in Arize: Common Issues

hello Arize team! Is there a recommended way to export & load traces that include evaluations? I have a parquet file that should include evaluations as well but when I load it in this way:

eval_df = pd.read_parquet("trace_dataset-5f7b8cf7-4fb0-4771-99cd-f519449cad80.parquet")
px_dataset = px.TraceDataset(eval_df, 'eval_df')
px.launch_app(trace=px.TraceDataset.load(px_dataset))

I get the attached error
