Unable to disable tracing

[danem]

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

This error also occurs when WEAVE_DISABLED is set.
