configuration while developing an shopify app using php template

[Webstollen]

i downloaded the repo here https://github.com/Shopify/shopify-app-template-php and followed the read.md(

php artisan key:generate

php artisan migrate
cd ..
yarn dev

) but got errorr "Couldn't find the store with domain ". but my store is running , i can click on the error message link to go to my store.

i think it's due to my config, i cant  find anything about configuring env and app.toml.

Shopify doesn't allow me to post my file here, i'll just describe it. in .app.toml  i just changed the name, handle to the app name i wantedand application_url to the url of my store.

thanks
