I am new to Shopify. I am using node js with same front ent, and back end domain xxx.ngrok.io to develop my app. I used '@shopify/app-bridge-react' to set App Context Provider with correct keys. Both component <TitleBar>, and <ResourcePicker> don't load for me without error thrown, while non-bridge other components loads.
I checked my 'app' is correct, and I see console error 'Failed to load resource: the server responded with a status of 404 ()' Not sure if this is related. How should I debug this ? Thanks !
