I have this error appearing in
/var/log/juju/machine-0.log in the controller instance.
2020-09-14 17:28:19 ERROR juju.worker.dependency engine.go:671 “mgo-txn-resumer” manifold worker returned unexpected error: cannot resume transactions: The update path ‘settings.’ contains an empty field name, which is not allowed.
2020-09-14 17:28:52 ERROR juju.worker.dependency engine.go:671 “api-caller” manifold worker returned unexpected error:  “machine-0” cannot open api: model cache: model “61909253-939f-48c0-8452-389111410e43” did not appear in cache timeout
Can anyone give some inputs if I should be concerned?
