Error generating HTML report. about fuzzbench

Sorry for the late response, I don't have a great guess. Do you want to email me [my last name]@chromium.org the data.csv.gz so I can try to reproduce?

Thanks a lot for the reply, but due to the error, report data isn't generated automatically after the experiment ends.

So, I modify the funcion, add_bugs_covered_column(experiment_df) in /fuzzbench/analysis/data_utils.py around line 153

def add_bugs_covered_column(experiment_df):
    """Return a modified experiment df in which adds a |bugs_covered| column,
    a cumulative count of bugs covered over time."""
    # Immediately return to avoid the code producing bugs
    experiment_df['bugs_covered'] = 0
    return experiment_df
    """
    if 'crash_key' not in experiment_df:
        experiment_df['bugs_covered'] = 0
        return experiment_df
    """
    grouping2 = ['fuzzer', 'benchmark', 'trial_id']
    grouping3 = ['fuzzer', 'benchmark', 'trial_id', 'time']
    df = experiment_df.sort_values(grouping3)
    # Bug Here
    df['firsts'] = (
        df.groupby(grouping2, group_keys=False).apply(is_unique_crash) &
        ~df.crash_key.isna())
    df['bugs_cumsum'] = df.groupby(grouping2)['firsts'].transform('cumsum')
    df['bugs_covered'] = (
        df.groupby(grouping3)['bugs_cumsum'].transform('max').astype(int))
    new_df = df.drop(columns=['bugs_cumsum', 'firsts'])
    return new_df

I will reproduce my experiment using the modified function and send it to you later.
If you want to run it yourself, my execution command is something like:

PYTHONPATH=. python3 experiment/run_experiment.py -b freetype2_ftfuzzer -c experiment-config.yaml -e <experiment name> -f aflplusplus

And my experiment-config.yaml:

# The number of trials of a fuzzer-benchmark pair.
trials: 1

# The amount of time in seconds that each trial is run for.
# 1 day = 24 * 60 * 60 = 86400
max_total_time: 7200

# The location of the docker registry.
# FIXME: Support custom docker registry.
# See https://github.com/google/fuzzbench/issues/777
docker_registry: gcr.io/fuzzbench

# The local experiment folder that will store most of the experiment data.
# Please use an absolute path.
experiment_filestore: /tmp/experiment-data

# The local report folder where HTML reports and summary data will be stored.
# Please use an absolute path.
report_filestore: /tmp/report-data

# Flag that indicates this is a local experiment.
local_experiment: true

Additional Information:

• I've searched for the error message and found a related website here.
• Besides, I checked the value of crash_key in experiment_df, they are None.

I am not sure if these would help.

same issue, have you fixed it?
