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. |
GraphDelegate |
Raised when a graph is delegated (for distributed mode). |
EmptyInputError |
Raised when graph receives an empty input. |
TaskNotFound |
Raised when the executor is unable to find a task (for distributed mode). |
CheckpointNotLatest |
Raised when the checkpoint is not the latest version (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 higher recursion_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: GraphBubbleUp
Raised when a graph is delegated (for distributed mode).
