In my case this meant my filter wasn't matching any of my running containers. Are you sure you have a container with name Container-Nginx, and did you mean to have two $ at the end of your filter?

[dsalnikov]

Had the same issue with wrong filter name.
Changing name helped.

[jeeftor]

How do you test the filter out?

How do we test the filter out? I'm having the same problem.
