我正在使用弹性搜索 Python API。我创建了一个名为“sample”的索引。但是，在尝试删除相同内容时遇到异常。下面是我的方法。
弹性搜索实例，
es = Elasticsearch("abc.def.ghi.jkl:9300")
检查索引是否存在
es.indices.exists(index="sample")
True
试图删除索引，
es.indices.delete(index="sample")
错误：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Donno 为什么会导致此错误。
