当我在本地运行时，我的应用程序运行良好。但是，一旦部署到 Heroku，服务器就停止返回数据并返回 500 代码。我的所有代码都可以在 here 中找到，并且实时应用程序（无法运行）是 here。
编辑： 这是heroku日志：
from pathlib import Path
import csv
csv_file = Path(Path.cwd(), ms_access_table_name + '.csv')
my_df.to_csv(csv_file, sep = ',', quoting=csv.QUOTE_NONNUMERIC , index=False)
ms_sql = f'INSERT INTO {ms_access_table_name} ({ms_access_columns}) \n' +\
f'SELECT {ms_access_columns} \n' + \
f'FROM [text;HDR=Yes;FMT=Delimited(,);IMEX=2;Database={Path.cwd()}].{ms_access_table_name + ".csv"}'
cursor.execute(ms_sql)
cursor.commit()
cursor.close()
conn.close()
