ERROR: Failed to set DPs

The problem

I have some automations that gradually change bulb colours and/or brightness. I had to change from using the cloud API to localtuya because they send too many API calls.

But since switching to localtuya I regularly get "Failed to set DPs" errors (see log example below). I know that the DP number and value are valid as I can use localtuya.set_dp to run the same change without an error.

Any idea what is causing this? Or how to fix it?

Environment

Localtuya version: 3.5.0
Home Assistant Core version: 2022.5.4
[] Are you using the Home Assistant Tuya Cloud component ?
[x] Are you using the Tuya App in parallel ? But only as a backup. We don't use it daily, and there's no automations on it.

Steps to reproduce

Have an automation that makes small changes to bulbs every few seconds.
Run it.
See errors.

Configuration `configuration.yaml` or `config_flow`

Here is the config for one of the affected bulbs:

- friendly_name: Bedside Lamp
  device_id: [REMOVED]
  local_key: [REMOVED]
  host: [REMOVED]
  protocol_version: "3.3"
  entities:
    - platform: light
      friendly_name: Bedside Lamp
      id: 20
      color_mode: 21 
      brightness: 22 
      color_temp: 23 
      color: 24
      brightness_lower: 10 
      brightness_upper: 1000 
      scene: 25
