Example script `script_use_zha_devices_response.yaml` results in error: `Error: Repeat 'for_each' must be a list of items`

[varenc]

I'm just trying to run this example script directly: https://github.com/mdeweerd/zha-toolkit/blob/main/examples/script_use_zha_devices_response.yaml

I get this error: Error: Repeat 'for_each' must be a list of items

Specifically on this part:

repeat:
  for_each: '{{ dev_data.devices }}'
  sequence:
     ...

Based on the logs dev_data.devices really looks like a Python/JSON list though. Tried to ... | list or ... | default([]) and still no luck. Can't figure out why it's not behaving list a list.
