I’m trying to get my second server configured for PMM 2.0. The first one was pretty painless, but when I try to “pmm-admin config” the second one I’m getting a message referencing “internal server error”. I’ve tried two different servers and the result is the same. I’ve looked at the pmm-managed log and there is a reference to a duplicate key - the .zip is attached. I’ve also added the “trace” output below. What am I doing wrong?
