Additional context

The issue is not seen when I make following changes to line number 860 of containerz_test.go to replace codes.FailedPrecondition with codes.NotFound

Original code:

} else {
t.Logf("Got expected error when starting with non-existent image %q: %v", pluginName, err)
s, ok := status.FromError(err)
if !ok || (s.Code() != codes.Unknown && s.Code() != codes.FailedPrecondition) {
t.Errorf("Expected gRPC status code Unknown or NotFound for non-existent image, got: %v (status code: %s)", err, s.Code())
}
}

Modified code:

} else {
t.Logf("Got expected error when starting with non-existent image %q: %v", pluginName, err)
s, ok := status.FromError(err)
if !ok || (s.Code() != codes.Unknown && s.Code() != codes.NotFound) {
t.Errorf("Expected gRPC status code Unknown or NotFound for non-existent image, got: %v (status code: %s)", err, s.Code())
}
}
