Cannot install from provided YAML

[q20]

Hi

I'm attempting to install:

https://github.com/m5stack/M5CoreS3-Esphome/blob/main/touch-and-sound/m5stack-cores3.yaml

…but the installer errors with:

INFO Reading configuration /config/esphome/m5stack-cores3.yaml...
INFO Updating https://github.com/m5stack/M5CoreS3-Esphome@None

This is without any YAML modifications.
Any ideas?
