i am trying update doctype but cannot update in database. when i log by (print() func). it work but nothing saved in database

func create new record in doctype history
async def createHistoryRecord(history, device):
	his_record = frappe.new_doc("Histories")
	his_record.device_id = device
	his_record.longitude = history['longitude']
	his_record.latitude = history['latitude']
	his_record.save()
	print("his:", his_record) // i print here and see doc update

func get data from other app


def getHistories(location):
    try:
        global histories 
        if location:
            histories.append(location)
            precessWebhookData()
    except Exception as e:
        return error_response(500, e)

func process data

def precessWebhookData():
    return asyncio.run(processHistoriesData())

async def processHistoriesData():
    try:
        global histories
        for history in histories:
            print("imei:")
            print(type(history['imei']))
            res_device_id = await getDeviceIdFromImei(history['imei'])
            print("device_id:")																																																						
            print(res_device_id)
            if True:
                print("hieu")
                print("ieu4")
                last_point = history
                print(last_point)
                device_id = res_device_id[0]['id']
                await updateDeviceLastPoint(device_id, last_point)
                print("OK!")
                dv = frappe.get_doc("Devices", {"imei": history["imei"]})
                await createHistoryRecord(history, dv.name)
            else:
