+			- **Run Configuration Type** - Python
+			- **Virtual Environment** - Select your project's virtual environment
+			- **Run Configuration Subtype** - `script`
+			- **Script Path**: absolute path to the `langgraph` executable within the virtualenv, found with `which langgraph`
+				- (anyone know how to make this more dynamic? just putting in `langgraph` yields `FileNotFoundError: [Errno 2] No such file or directory: 'langgraph'`
+			- **Script Parameters**: `dev`
+				- no need for `--debug-port`, which is for  [[Py/debugpy]]  instead of PyCharm's  [[pydevd]]

+# How to handle langgraph's blocking error
+	- ## sample error - "LangGraph dev identified a synchronous blocking call in your code"
+		- ```
+		  Heads up! LangGraph dev identified a synchronous blocking call in your code. When running in an ASGI web server, blocking calls can degrade performance for everyone since they tie up the event loop.
+		  Here are your options to fix this:
+		  1. Best approach: Convert any blocking code to use async/await patterns
+		     For example, use 'await aiohttp.get()' instead of 'requests.get()'
+		  2. Quick fix: Move blocking operations to a separate thread
+		     Example: 'await asyncio.to_thread(your_blocking_function)'
+		  3. Override (if you can't change the code):
+		     - For development: Run 'langgraph dev --allow-blocking'
+		     - For deployment: Set 'BG_JOB_ISOLATED_LOOPS=true' environment variable
+		  These blocking operations can prevent health checks and slow down other runs in your deployment. Following these recommendations will help keep your LangGraph application running smoothly!
+		  ```
