I created an app with the the shopify CLI that works fine with ngrok. But when I go deploy it on heroku I get the error message: C:/Ruby27-x64/lib/ruby/gems/2.7.0/gems/shopify-cli-2.2.2/vendor/deps/smart_properties/lib/smart_properties.rb:154:in `initialize’: ShopifyCli::Resources::EnvFile requires the following properties to be set: secret (SmartProperties::InitializationError).
I used the command shopify node deploy heroky and that succeeded but when I open the app I get this error. The env file is complete and changed with the heroku url. There are no quotes in the env file. Als added the heroku config variabels manualy in the heroku application.
for the secret I have the following. The system gives no feedback on the API_KEY, SCOPES or Host.
SHOPIFY_API_SECRET_KEY=shpss_…etc
