我在我的 python 脚本（plotly dash 应用程序）中使用 python 雪花连接器，今天该应用程序停止工作而我没有更改代码。我尝试了几件事来找出可能是什么问题，我什至尝试运行Snowflake 文档中的示例代码，但遇到了同样的错误：

代码：

cur = conn.cursor()
try:
    cur.execute("SELECT col1, col2 FROM test_table ORDER BY col1")
    for (col1, col2) in cur:
        print('{0}, {1}'.format(col1, col2))
finally:
    cur.close()

错误：

Traceback (most recent call last):
