Silk + cacheops not working

[tunecrew]

Env is Django 2.1.2 w/ uwsgi on Python 3.6 in the python alpine docker image. DB is MariaDB 10.3 in a different docker image.

Silk runs fine but if I enable cacheops I get the following error + traceback at /silk/ (cacheops works fine w/o silk)

FieldError at /silk/

Also experiencing this. I commented out the "cacheops" in my INSTALLED_APPS as a temporary measure and silk now appears to work.
