Update `apps/dojo/README.md` to make it work

[taoari]

If one is following the README.md under apps/dojo, it simply does not work. The first issue encountered is described in #59. However, following the solution in that issues simply raises more issues. It would be great if this README.md could be updated.

@taoari, please post the error you are seeing.

Hi ! Same here 🙂
I wanted to make the demo running locally to play a bit with its code but I'm not able to make it run.

Console is full of module not found messages:

Uncaught Error: Module not found: Can't resolve '@ag-ui/middleware-starter'

Uncaught Error: Module not found: Can't resolve '@ag-ui/server-starter'

and so on...

Looks like a tsconfig path resolution failing.

I also had the

$ npm i turbo
npm error code EUNSUPPORTEDPROTOCOL
npm error Unsupported URL Type "workspace:": workspace:*

Wow, yes a lot of this is very out of date, I can take a moment to clean it up.

Re: npm error code EUNSUPPORTEDPROTOCOL

The dojo as it is now pretty much requires the use of pnpm vs just npm, I can probably add something for that (in addition to cleaning up the docs)

[sdedieu]

If you can add the steps for having the demo to run on a fresh computer that would be lovely!

Not perfect, but a huge leap forward.

Thank you for the update 👍

I gave a try this morning. Sadly both the ./scripts/prep-dojo-everything.js and ./scripts/run-dojo-everything.js exited with code 0. Got some huge json objects array in the logs.

So I tried with running the demo viewer, and run the agent(s) separately.

As I wanted to have the shared-state demo running locally, I did run:

• pnpm dev at the dojo folder level successfully ran the demo frontend. ✅
• npm run dev in the integrations/langgraph/typescript folder, it worked ✅

But then I got the following errors in the console:

CopilotKit Error (hidden in production): Agent 'shared_state' failed to execute: fetch failed

Error in async callback: Error: Failed to retrieve assistant: fetch failed
    at eval (chunk-OT5NHMEC.mjs:296:19)
    at Generator.next (<anonymous>)
    at fulfilled (chunk-SKC7AJIV.mjs:45:24)

My guess was that it needed also the python to be running.

But running poetry install && poetry run dev on the integrations/langgraph/python folder led to a ModuleNotFoundError: No module named 'fastapi'error I didn't managed to solve 😅

EDIT:

For the "Run just the demo viewer, and run the agent(s) separately."

I was running npm run dev inside of the ag-ui/integrations/langgraph/typescript instead of ag-ui/integrations/langgraph/typescript/examples/src/agents/agentic_chat.

It then asked me to rename .env.example file into .env and fill up the OPENAI_API_KEY and LANGSMITH_API_KEY. I got it working just fine now.

(Use the dojo-everything scripts issue persist though).
