Error starting frontend

mistamun · January 8, 2025, 11:59pm

I’m a little lost here, what am I missing? the debug loglevel doesn’t give me any extra info.

Has anyone seen a similar issue? This started to happen in my app but can be replicated even with the blank template as shown below:

Is there a way to lock the frontend packaging too? Cause this sort of unexpected change has happened to me more than once now and it’s really annoying because I don’t see how to control it (or fix it)

sumanth · January 10, 2025, 12:50pm

Hi @mistamun Could you try to run “reflex run --loglevel debug” and share the info you are getting there?

I have somehow fixed the issue although I’m not sure exactly what is happening.

This is a conda env (just for python) and poetry.
the conda env looks like:

name: reflex-dash
channels:
  - conda-forge
  - nodefaults
dependencies:
  - python=3.12.3

When running reflex run for the first time there are a few warnings about certificates being out of date (for tailwind and others), that’s what those bun errors are.
