Community Feedback for CryptoDappy Beta

Hi Ben, I’m not sure if it’s on my end or not, but when I click on the test app ( and I click “Sign In” – I get a blank white box. I’ve tried different browsers and I still get the same blank white box. Are you seeing the same behaviour?


same… not sure what happened… I’m really anxious to learn this and personalize it to use for my family.

Ben can you help?

Hi @bebner - I’ve completed mission #2 but ran into a strange error when trying to retrieve the list.

Access to fetch at '' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.


I’ve found no way in the docs to change the mode for local development. Any ideas?

Thank’s a lot!
