chore(deps): bump the langgraph group across 1 directory with 2 updates

[dependabot]

Bumps the langgraph group with 2 updates in the / directory: @langchain/langgraph and @langchain/langgraph-checkpoint-sqlite.

Updates @langchain/langgraph from 1.3.7 to 1.4.2

Release notes

Sourced from @​langchain/langgraph's releases.

@​langchain/langgraph@​1.4.2

Patch Changes

• #2527 9e114e5 Thanks @​christian-bromann! - chore(deps): remove uuid dependency in favor of embedded uuid in core

  Replace direct uuid package imports with @langchain/core/utils/uuid across langgraph packages to deduplicate dependencies and align with @​langchain/core's embedded UUID utilities.

• Updated dependencies [ba31f04, e7e8035, 9e114e5]:

  • @​langchain/langgraph-sdk@​1.9.22
  • @​langchain/langgraph-checkpoint@​1.1.1

@​langchain/langgraph@​1.4.1

Patch Changes

• #2520 2da5c33 Thanks @​christian-bromann! - fix(state): validate Zod state updates from nodes

  Validate node return values and Command updates against Zod state schema constraints before applying them to graph state.

  Fixes #2519

• #2511 ef04db3 Thanks @​christian-bromann! - feat(ToolNode): forward graph state to tools via runtime.state

  ToolNode now forwards its input to each tool through the second argument as runtime.state. When using ToolNode as a node in a LangGraph graph, this gives tools access to the current graph state for workflows that need tool-call support in LangGraph proper. Tools can type the second parameter as ToolRuntime<StateType> from @langchain/core/tools and read runtime.state directly. This works in every runtime, including web browsers, and removes the need for getCurrentTaskInput() (which relies on node:async_hooks/AsyncLocalStorage). getCurrentTaskInput(config) continues to work for backwards compatibility.

• Updated dependencies [3855985, 7c3e9e9, 17c44a3]:

  • @​langchain/langgraph-sdk@​1.9.21

@​langchain/langgraph@​1.4.0

Minor Changes

• #2449 d12d269 Thanks @​christian-bromann! - Add cooperative, between-superstep graph draining via RunControl.

  A new RunControl (exported from @langchain/langgraph) exposes requestDrain(reason) plus read-only drainRequested / drainReason. Pass it through the new control option on invoke / stream / streamEvents (and the functional API). It is surfaced on runtime.control, so nodes can read it or call requestDrain() themselves, and it is propagated into subgraphs.

  When a drain is requested, the Pregel loop checks the flag at the top of each superstep (after the previous step's writes are applied and checkpointed): if more tasks remain it saves the checkpoint and throws the new GraphDrained error (also under durability: "exit"), so the run can be resumed later from the same config. If the graph naturally finishes on that tick it returns normally and the caller can inspect control.drainRequested. A drain requested inside a subgraph bubbles up and stops the parent at its next boundary. Draining never cancels work that is already running — pair it with an AbortSignal if you need a hard upper bound.

Updates @langchain/langgraph-checkpoint-sqlite from 1.0.2 to 1.0.3

Release notes

Sourced from @​langchain/langgraph-checkpoint-sqlite's releases.

@​langchain/langgraph-checkpoint-sqlite@​1.0.3

Patch Changes

• #2516 f6a6d26 Thanks @​jackjin1997! - fix: SqliteSaver.putWrites now honors WRITES_IDX_MAP, pinning special channels (__error__, __scheduled__, __interrupt__, __resume__) to fixed negative indices instead of the call-local ordinal. Previously a follow-up putWrites([[INTERRUPT, …]], taskId) for the same checkpoint silently REPLACEd the regular write previously stored at idx=0 for that task, losing data. The conflict-resolution clause also now matches the Python checkpointer contract: OR REPLACE only when every channel is a special one (so e.g. INTERRUPT→RESUME state transitions overwrite), OR IGNORE otherwise.
