What happened?

Traceback (most recent call last):
File "", line 198, in _run_module_as_main
File "", line 88, in _run_code
... sys.exit(main())
... return POST_CONFIG_ACTIONS[args.command](args, config)
... exit_code = write_cpp(config, native_idf=native_idf)
... init_sequence = flatten_sequence(init_sequence)
... for x in sequence

TypeError: 'NoneType' object is not iterable

How to reproduce

1.) Minimal Yaml:
esphome:
name: test

esp32:
board: esp32-s3-devkitc-1
framework:
type: arduino

spi:
id: spi_bus
clk_pin: GPIO5
mosi_pin: GPIO4

display:

• platform: epaper_spi
  model: JD79660
  dimensions:
  width: 800
  height: 480
  cs_pin: GPIO10
  dc_pin: GPIO09
  reset_pin: GPIO01
  busy_pin:
  number: GPIO03
  inverted: True
  update_interval: never

2.) Valid but compiling error
3.) Debugging with copilot, Gemini and ChatGPT, (GPIOS, framework, display settings, borads...., syntax) - no success
4.) Testet with standallone 2025.12 - no success

Expected behavior

compailing without errors
