### What problem does this PR solve?

Fix a small non-blocking main workflow bug about chunk update When
OpenSearch is the doc engine.
When you wanna enable/disable a chunk in the web-page “Knowledge Base /
Dataset / Chunk”, the bug ocurred.

src="https://github.com/user-attachments/assets/575987a0-c929-4589-bfa0-ba54e137cfd9"
/>

The reaseon why it ocurred is that some api params between OpenSearch
and ES differs. It functioned well no matter enable/disable/rewrite the
chunk after I fixed. I also checked the result when using the chat
web-page.

I will still focus on vector-database espeically OpenSearch.
