Reflex run failed then remove my whole code #3747

Open leehuwuj opened 3 months ago

leehuwuj commented 3 months ago

Describe the bug I ran into this issue twice and it looks a serious bug to me which reflex remove almost my whole code folder. Here is my project structure:

app/
  api/
  services/
  ui/ => reflex code here
  app.py
rxconfig.py

After ran reflex run it created a .web folder in the project root path. But it instantly got error then remove everything in the app folder.

Rxconfig code:

# rxconfig.py
import reflex as rx

config = rx.Config(
    app_name="app",
)

Here is the log:

leehuwuj commented 3 months ago

Additional note: Fortunately, my project has initialized Git so i just need to revert the deleted changes. Then i reran reflex run again and it worked nicely.

masenf commented 3 months ago

Is there anything unusual in your app, like changing reflex.constants values? or threads modifying the assets folder?

I'm trying to figure out how to reproduce this issue, which appears to be related to the assets folder monitoring. If you know what I can do to trigger this, please let me know, would like to fix it.

leehuwuj commented 3 months ago

@masenf thank for the response. It seems like it just happened randomly, and nothing affected the constant values or changing the assets either. But if i disabled telemetry then the issue doesn't come up anymore.

import reflex as rx

config = rx.Config(
    app_name="app",
    telemetry_enabled=False,
)

I'll share the code with you later so you can try to reproduce the issue. In the meantime, I hope you can spot a bug with the sign above! Feel free to discuss if you need more information.
