Thank you for time and consideration!

Based on the provided information, there doesn't seem to be any issue with starting the backend server using uvicorn. The server is running successfully on http://127.0.0.1:3000, and the application startup has completed without any errors.

However, since you mentioned starting both the backend and frontend, it's possible that there could be an issue with the frontend part (npm start). The output provided here only pertains to the backend server. If you are encountering any issues with the frontend, please provide additional information or error messages related to that part of your application.

@linxule the 500 errors are suspicious. There should be some logs from uvicorn--can you share those?

[linxule]

For Frontend, Error message in the browser is "ERROR: Failed connection to server. Please ensure the server is reachable at ws://localhost:3001/ws."

For Backend, there seems no be no error:

[rbren]

Try adding --host 0.0.0.0 to the uvicorn command

uvicorn opendevin.server.listen:app --port 3000 --host 0.0.0.0

[linxule]

Backend works.

Encountered the same error with frontend.

I have also enabled Allow the default Docker socket to be used (requires password) on Docker Desktop.

[foragerr]

I believe I have the same issue. The backend server starts fine at port 3000

The frontend comes up on port 3001, then tries to connect to http://localhost:3001/api/litellm-models and receives a HTTP500. Note the port in that url, shouldn't it be connecting to the backend on port 3000, rather than trying to reach a 3001 url?

The node app proxies http://localhost:3001/api/litellm-models to http://localhost:3000/litellm-models here

[foragerr]

but then the /api path doesn't exist on the backend either..

curl -I http://localhost:3001/api/litellm-models
HTTP/1.1 500 Internal Server Error


curl -I http://localhost:3000/api/litellm-models
HTTP/1.1 404 Not Found


curl http://localhost:3000/litellm-models
["gpt-4","gpt-4-turbo-preview","gpt-4-0314","gpt-4-0613", .... ]

[linxule]

I tested the endpoint and got

curl -I http://localhost:3001/api/litellm-models
HTTP/1.1 500 Internal Server Error

Was working earlier, but did git pull, did npm install for client and pulled the new docker image - now the same problem as above.

[foragerr]

tl;dr: downgrade to node 16 and it works again.

[foragerr]

The issue seems to be related to this change from a few hours ago: 1ae3f1b

And the cause seems to be this issue: nodejs/node#40537

I don't know the proper fix, but downgrading node to v16 goes around the issue by using localhost instead of [::1] as the backend destination address.

[foragerr]

Alternatively, for node 17+, start your backend with:

uvicorn opendevin.server.listen:app --host '::' --port 3000

uvicorn opendevin.server.listen:app --host '::' --port 3000

@foragerr amazing. thank you so much for this!

[xcodebuild]

It seems that localhost cannot proxy correctly on node17+. Simply replace it with 127.0.0.1 works. I have opened a pull request: #535
