How to display an error message when pd.read.csv fails

Question

I use pd.read_csv to fetch GCS data.
However, when the file size is too large or something, the python task force quit automatically at the line using pd.read_csv without displaying the error message.
I would like to display an error message to improve the script and catch the error. How can I do that?

    appended_data = []
    print('loop start')
    for blob in self.client.list_blobs(self.bucket, prefix=prefix):
        if re.match(regexp_file_path, blob.name):
            print('fetch')
            df = pd.read_csv('gs://{}/{}'.format(self.bucket, blob.name), names=columns, sep='\t')
            print('append')
            appended_data.append(df)

    print('loop end')

and, the result is below

loop start
fetch
append
fetch
append
fetch
append
fetch
append
fetch
append
fetch

I expected the script prints "append" and "loop end", but the script force quits with the last message "fetch".
