Closes [#1808](https://github.com/langchain-ai/langgraphjs/issues/1808). ## @langchain/langgraph-checkpoint-postgres@1.0.4 ### Patch Changes - [#2566](https://github.com/langchain-ai/langgraphjs/pull/2566) [`091a46f`](https://github.com/langchain-ai/langgraphjs/commit/091a46f32ddd3a85ee89e35fb9ea953dfc4cf8b4) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph-checkpoint-postgres): prevent createAgent failures with PostgresSaver Add BaseCheckpointSaver.toJSON() so ConfigurableModel can stringify runnable config without traversing pg Pool timers, and default missing checkpoint maps on load/copy so resume no longer crashes on undefined versions_seen.

Other loaders default to `--import`; only registered shorthands like `ts-node` use `--loader`. `--no-reload` now also disables tsx's internal watch mode.

This fixes `ERR_REQUIRE_ESM` for CommonJS consumers on Node versions where `require(ESM)` is not enabled by default (< 20.19 / < 22.12).
