New error: .GetModelConstraints is not implemented

Out of the blue, I began receiving this message from juju when deploying a new charm. Adding a unit works with no issue. What little I could find on this error pointed me here. Have any of you seen this?

juju deploy redis --to lxd:341 ERROR no such request - method ModelConfig(2).GetModelConstraints is not implemented (not implemented)

snaps juju 3.0.0 21122 latest/stable canonical✓ - maas 3.2.7-12037-g.c688dd446 26274 3.2/stable canonical✓

OS ubuntu 18.04

Does this also happen with juju 3.0.3 client? What is the version of the juju controller (juju status -mcontroller)?
