Prefect Community

Hello everyone, I started getting a warning for each task in any of my flows, logging: “can’t use cache because it is now invalid”
The odd thing is that I am not using caches at all. This warning should be triggered `if task.cache_for is not None` according to the `task_runner.py` source code. I double checked that all my tasks have a `cache_for` value of `None`.
I’ve been away from Prefect for about a month and don’t remember getting this warning at all, And I haven’t changed versions. Has anyone experienced a similar issue?

Hey Emre, that message was a bug accidentally introduced in 0.6.0! It's been fixed in 0.6.1. Fortunately it's just a message, not affecting functionality. 

Although if you haven't changed versions that's interesting :thinking_face:  

I believe that message (and related bug) are only in 0.6.0

Yeah turns out i did change :sweat_smile:. Forgot that I was working on a new project with a fresh virtualenv. I’ll upgrade right away.
