Weave Version: 0.51.28  
Python version: 3.12.8

In my application I want to enable tracing via feature flag:  
if is\_tracing\_enabled:  
weave.init(project\_name)  
else:  
weave.init(project\_name, settings={‘disabled’:True})  
# weave.init(project\_name, settings=UserSettings(disabled=True))

This results in the following error when calling a function decorated with `weave.op`:

ERROR:weave.trace.concurrent.futures:Task failed: HTTPError: 400 Client Error: Bad Request for url: [https://trace.wandb.ai/files/create](https://trace.wandb.ai/files/create)

This error also occurs when `WEAVE_DISABLED` is set.
