I get this error when I try to run the project

index.vue?6ced:48 User denied web3 access Error: Provided address null is invalid, the capitalization checksum test failed, or it's an indirect IBAN address which can't be converted. at Method.inputAddressFormatter

This means the app does detect that you have the Metamask extension on your browser, but that you haven't connected to any address with it. The "User denied web3 access" is displayed in the console when that is the case.

I have updated to tutorial (and repo) so that the error is explicitly displayed on the page as well.

Thank you for your question! Don't hesitate if you have any other!

I've added a pull request that makes the app more intuitive by automatically asking for connecting the address.
