I had SCOUT_LOG_LEVEL set to WARN, but that error is super opaque on what's happening.

Also, is 'warn' not a valid log level? or is it the all caps that tripped it up?

Happy to rename the error; but the key should indeed be warning not warn, see:

These are the standardised log levels in PHP...

It'd be great if we can clarify the error message and give the user a pointer on how to fix it.

Yup, I can definitely do that!
