[Error] Unable to Build Langgraph Project

[Toubat]

Hi LangChain team,

I tried to connect my langgraph project to the desktop and got the following error which I don't fully understand:

After double-check, I found that my project works on both langgraph deployment and using the local CLI langgraph up, but fails on the langgraph desktop app. Do I need some additional steps for using the desktop app?

I also tried deleting all existing images, containers, builds, etc and re-run but seems getting the same error above. Is there any steps I'm missing?

Below is my project structuure:

.
├── agent-graph
│   └── agent_graph
├── agent-server
│   ├── agent_server
│   ├── logs
│   └── tests
├── client
│   ├── app
│   ├── components
│   ├── hooks
│   ├── lib
│   ├── node_modules
│   └── public
├── libs
│   └── libs
└── notebooks
├── langgraph.json
├── poetry.lock
├── .env
└── pyproject.toml

and here's my langgraph.json:

{
  "dockerfile_lines": [],
  "graphs": {
    "my-agent": "./agent-graph/agent_graph/agent.py:graph"
  },
  "env": ".env",
  "dependencies": ["./agent-graph", "./libs"]
}

Same issue here -- didn't change anything, just upgraded to the .20 build of LangGraph Studio, and I'm getting the errors above whereas it all worked pre-upgrade
