Hi, there are some issues trying to implement this template to the project I am working on.

When I import this project straight into my project without any modification, it returns such error.

Invalid assistant ID

There is no problem running the memory state separately, and I've figured that it is a problem with get_client() not being able to run in the background. I've tried inputting url parameter as http://localhost:8123, yet the error changes to ConnectError('All connection attempts failed') but does not fix.

what possibly could happen here? All I did was to copy paste the code into my repository, changed the import to absolute path, and all the models to openAI. the same code works perfectly in the template.

I've been trying to run the template using langgraph up and the debugger. but it seems like the memory isn't updating when I use this method. It runs perfectly on the desktop CLI. But when I use the debugger and langgraph up command I get this error, resulting in memories not getting updated

@wkdghdus commented on GitHub (Oct 17, 2024):

I've solved this problem by modifying langgraph.json file.

I've initially assigned the graph names like these
"convo/chatBot": "path/to/chatbot/graph.py:graph"
"convo/memoryGraph": path/to/memory/graph.py:graph"

I think this for some reason hindered the ability for get_client to fetch the memory graph.
(I have no idea how get_client() fetches the correct graph without any specification)

but when I changed the graph names to "chatBot" "memoryGraph", it worked as intended.

can somebody possibly explain why this solution worked?

It's https://github.com/langchain-ai/memory-template/blob/141b1b0afff40b5cea79212b9fa5cc9be58f26ef/src/chatbot/configuration.py#L17

the assistant ID configuration value can etiher be a graph name or an assistant.
