Web BT: GATT operation already in progress

Hi, I’m trying to use web bluetooth to configure a particle device:

simpleiot/simpleiot/blob/master/frontend/public/ble.js

const serviceUuid = "5c1b9a0d-b5be-4a40-8f7a-66b36d0a5176";
const charUptimeUuid = "fdcf0000-3fed-4ed2-84e6-04bbb9ae04d4";
const charSignalUuid = "fdcf0001-3fed-4ed2-84e6-04bbb9ae04d4";
const charFreeMemUuid = "fdcf0002-3fed-4ed2-84e6-04bbb9ae04d4";
const charModelUuid = "fdcf0003-3fed-4ed2-84e6-04bbb9ae04d4";
const charWifiSSIDUuid = "fdcf0004-3fed-4ed2-84e6-04bbb9ae04d4";
const charConnectedUuid = "fdcf0005-3fed-4ed2-84e6-04bbb9ae04d4";
const charSetWifiSSIDUuid = "fdcf0006-3fed-4ed2-84e6-04bbb9ae04d4";
const charSetWifiPassUuid = "fdcf0007-3fed-4ed2-84e6-04bbb9ae04d4";
// Const charDeviceNameUuid = "fdcf0008-3fed-4ed2-84e6-04bbb9ae04d4";
const charTimerFireDurationUuid = "fdcf0009-3fed-4ed2-84e6-04bbb9ae04d4";
const charTimerFireUuid = "fdcf000a-3fed-4ed2-84e6-04bbb9ae04d4";
const charCurrentTimeUuid = "fdcf000b-3fed-4ed2-84e6-04bbb9ae04d4";
const charTimerFireTimeUuid = "fdcf000c-3fed-4ed2-84e6-04bbb9ae04d4";

export class BLE {
  constructor(stateChanged) {
    this.resetState();
    this.stateChanged = stateChanged;
  }

However, I’m occasionally getting this message in the browser:

configure GW configure Timer error: DOMException: GATT operation already in progress.

This thread has some information on it as well:

Has anyone else dealt with this of know of an example of how to handle it?
