📄 Description

Summary

Fixes broken code example in the BigQuery callback handler integration docs.

Closes #3509

Problem

With langchain-google-community==3.0.5, the Use with LangGraph Agent
section raises two errors:

Error 1 — graph_name is not a valid constructor parameter:
TypeError: BigQueryCallbackHandler.init() got an unexpected keyword argument 'graph_name'

Error 2 — graph_context() method does not exist:
AttributeError: 'BigQueryCallbackHandler' object has no attribute 'graph_context'

[screenshot attached below]

Root Cause

The docs example references graph_name and graph_context() which were
never part of the BigQueryCallbackHandler API in v3.0.5.

Actual constructor signature:
BigQueryCallbackHandler(project_id, dataset_id, table_id=None, config=None)

Fix

  • Removed non-existent graph_name argument from constructor
  • Removed non-existent graph_context() context manager
  • Handler is passed directly via config={"callbacks": [handler]}
