Originally created by @robertszalai on GitHub (Oct 13, 2024).

I try to pass RunnableConfig to a tool used with ToolNode. I create the tool with tool() and as I see in the source code if there's no schema or I use a string schema a DynamicTool is created instead of DynamicStructuredTool. The tool is invoked with (input, runManager, config), but with DynamicTool the config is not passed correctly, because it doesn't have a wrapper as with DynamicStructuredTool. The result is that the second (config) param in my tool function is undefined.
