There was a problem hiding this comment.
While this achieves what we want, a more concise way that this can be written is:
Suggested change
| is_ignored = isinstance(error, tuple(LangchainIntegration._ignored_exceptions)) | |
| is_ignored = type(error) in LangchainIntegration._ignored_exceptions |

Description
Close the active span without setting an error status and do not capture an exception if
GraphBubbleUpis handled. The exception is a LangGraph control-flow type.Since the error hooks live on the LangChain layer, add a private set that the LangGraph integration uses to inform the LangChain integration that
GraphBubbleUpshould be ignored. This prevents semantics from the LangGraph library leaking into the LangChain integration.Issues
Closes #6384
