Error: Could not find one of 'package.json' manifest files in the package

Hi, I want to make this Tag Reader for my Daugther with special needs in communication, using my Home Assistant.

if I use web.esphome.io I can prepare the ESP Device and add the WiFi credential with no error. After I see it on my ESPHome AddOn and I press "Adopt"... no errors.

Now I start to see the error. if I try to add the API key or the tagreader.yaml file I seen all time this error:

INFO Reading configuration /config/esphome/esphome-web-14e0e2.yaml...
INFO Generating C++ source...

Error: Could not find one of 'package.json' manifest files in the package

and this the main config installed by the web tool:

board: esp01_1m
