Per the LangChain v1 migration guide, the hub module moved from the langchain package to langchain-classic. Two integration docs still show the old import, which raises ImportError: cannot import name 'hub' from 'langchain' under LangChain 1.0+. Affected files: - src/oss/python/integrations/retrievers/egnyte.mdx - src/oss/python/integrations/tools/ibm_watsonx_sql.mdx
