OBSFileLoader.load() didn't seperate file content as expect

[Junon-Gz]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from obs import ObsClient
from langchain_community.document_loaders import OBSFileLoader
client = ObsClient(access_key_id=ak, secret_access_key=sk, server=server)
obs = OBSFileLoader(bucket,key_name,client,endpoint)
obs.load()

#[Document(metadata={'source': 'whole content of in `key_name` file')]

Error Message and Stack Trace (if applicable)

No response

Description

• I expect to see [Document(metadata={'source': 'segment 1'),Document(metadata={'source': 'segment ')...]
• Instead, [Document(metadata={'source': 'whole content of file')]
