Errors¶
Classes:
| Name | Description |
|---|---|
GraphRecursionError | Raised when the graph has exhausted the maximum number of steps. |
InvalidUpdateError | Raised when attempting to update a channel with an invalid set of updates. |
GraphInterrupt | Raised when a subgraph is interrupted, suppressed by the root graph. |
NodeInterrupt | Raised by a node to interrupt execution. |
EmptyInputError | Raised when graph receives an empty input. |
TaskNotFound | Raised when the executor is unable to find a task (for distributed mode). |
Bases:RecursionError
Raised when the graph has exhausted the maximum number of steps.
This prevents infinite loops. To increase the maximum number of steps,run your graph with a config specifying a higherrecursion_limit.
Troubleshooting Guides:
Examples:
graph = builder.compile()graph.invoke( {"messages": [("user", "Hello, world!")]}, # The config is the second positional argument {"recursion_limit": 1000},)
Bases:Exception
Raised when attempting to update a channel with an invalid set of updates.
Troubleshooting Guides:
Bases:GraphBubbleUp
Raised when a subgraph is interrupted, suppressed by the root graph.Never raised directly, or surfaced to the user.
Bases:GraphInterrupt
Raised by a node to interrupt execution.
