First time I run the simulation, it shows "Please start the backend first."

[Leon1Wei]

As title says, I tried over and over again, it still shows Please start the backend first.

Have you already started the web server via python manage.py runserver?

[SergeyAP]

Same issue for me. @xcfcode yes, backend's process is working. Also I get an issue to backend's log: Klaus Mueller persona.scratch.importance_trigger_curr:: 145 150 aldhfoaf/???? the Ville:Dorm for Oak Hill College:Klaus Mueller's room:bed Traceback (most recent call last): File "/Users/zachem/projects/generative_agents/reverie/backend_server/reverie.py", line 468, in open_server rs.start_server(int_count) File "/Users/zachem/projects/generative_agents/reverie/backend_server/reverie.py", line 401, in start_server with open(curr_move_file, "w") as outfile: FileNotFoundError: [Errno 2] No such file or directory: '../../environment/frontend_server/storage/112/movement/0.json' Error. backend is continue working

Are you running both the frontend and backend on the same computer?

This issue is known, and documented in issue #2

[SergeyAP]

Are you running both the frontend and backend on the same computer?

Yes, I've tried that on two VMs and the result is the same

[SpencerWF]

Okay, are you sure the VM can access it's own server? Can you try without the VM? I think it might be that a disconnection between your backend and your frontend is the issue.

[HananJackie]

I believe I have the same issue. everything works up until step 3.

with python 3.10 - the first time I open chrome on http://localhost:8000/simulator_home it shows "Please start the backend first." with python 3.9 - the first time I open chrome on http://localhost:8000/simulator_home it shows the map and the characters details, without any ability to scale the map. Once I refresh the browser it says "Please start the backend first.".

same problem

[TommyZihao]

This bug only happens when you run for the first time. To fix this bug, just need to close all terminal, and restart from the python manage.py runserver.

i modify the meta.json in storage/ project / reverie/ change the "step" and "curr_time" so the simulation can continue. i got this problem when i close / reopen my laptop and reopen the browser, then the connection failed, and i stuck here

same issue — any fix?
