Can't discover service, and then 'org.bluez.Error.Failed' after a minute

I’m using RPi 4 (with node 14.9.0, BlueZ 5.50). I can discover the device, but not the service.

require('dotenv').config()

const { createBluetooth } = require('.')
const { TEST_DEVICE, TEST_SERVICE, TEST_CHARACTERISTIC, TEST_NOTIFY_SERVICE, TEST_NOTIFY_CHARACTERISTIC } = process.env

async function main () {
  const { bluetooth, destroy } = createBluetooth()

  // get bluetooth adapter
  const adapter = await bluetooth.defaultAdapter()
  await adapter.startDiscovery()
  console.log('discovering')

  // get device and connect
  const device = await adapter.waitDevice('D4:CA:6E:F1:84:BE')
  console.log('got device', await device.getAddress(), await device.getName())
  await device.connect()
  console.log('connected')

  const gattServer = await device.gatt()

  // read write characteristic
  const service1 = await gattServer.getPrimaryService('15172000-4947-11e9-8646-d663bd873d93')
  console.log('got primary service.')
  const characteristic1 = await service1.getCharacteristic('15172001-4947-11e9-8646-d663bd873d93')
  console.log('got control characteristic.')
  //await characteristic1.writeValue(Buffer.from('Hello world'))
  const buffer = await characteristic1.readValue()
  console.log('read', buffer, buffer.toString())

}

main()
  .then(console.log)
  .catch(console.error)

Console output

I was using Raspberry Pi 3 and 4. Upgrading to the latest version of Raspbian (Raspberry Pi OS) solved the problem for me.

In order to debug the issue, I suggest you the following lines:

$  bluetoothctl
> connect DC:A6:32:3F:7B:7A
> menu gatt
> list-attributes

Does bluetoothctl list the expected services?

I get the same problem. I’m running in a Docker Image on a RPi4.

I can ssh into the docker image and when I try https://github.com/chrvadala/node-ble/issues/13#issuecomment-761858089 I get the following :

[bluetooth]#
[CHG] Device 7B:41:00:00:04:98 ManufacturerData Value: 0x00
[bluetooth]#
[CHG] Device 7B:41:00:00:04:98 ManufacturerData Value: 0x00
[bluetooth]# connect 7B:41:00:00:04:98
Attempting to connect to 7B:41:00:00:04:98
[bluetooth]#
Failed to connect: org.bluez.Error.Failed
[bluetooth]#

In my code, I can get the device, and getAddress and getName work as expected, but when I attempt to connect, I get :
