Web BLE clearing credentials

Firmware

When clearing WiFi credentials from a Photon2 / OS 5.7.0 using an extended version of ble_wifi_setup_manager library the following errors are after what is a successful clearing of credential. Can anyone help throw light on what these errors are?

0000054252 [app.BLEWiFiSetupManager] TRACE: Added message to the queue: {"msg_type":"clr_creds"}

I am using the same approach (disconnecting from cloud and WiFi before deleting) from Photon to reliably clear the credentials and maybe this is the problem.

That error is generated here:

It looks like it occurs when the interface is down (because it sounds like you disconnected) but the link is still up. I'd guess that it's because the the disconnect hasn't finished yet.

However, it also is in a function to send data, so it's probably not an important error, as if the interface is in the process of disconnecting you probably don't care that data is getting discarded.

Thanks
Next question, should I check for completion? There are new functions in Device OS 5.X.0?

uint32_t time_out_cloud = 2000;
if (Particle.connectionInterface() == WiFi) {
    time_out_cloud = 5000;
} else if (Particle.connectionInterface() == Cellular) {
    time_out_cloud = 20000;
} else if (Particle.connectionInterface() == Network) {
     time_out_cloud = 2000;
}

Particle.disconnect(CloudDisconnectOptions().graceful(true).timeout(time_out_cloud));
waitFor(Particle.disconnected(), 2000);  //is this now redundant?

And

WiFi.disconnect();
waitFor(!(WiFi.ready()), 1000);

Or can I just clear the credentials and this will disconnect the WiFi?
