Errors when dfx build with the Linkedup tutorial

I’m looking for this too. I was previously using LinkedUp as a solid example of how to build a working app on the Internet Computer, but now it’s failing to build (dfx 0.8.4). Is there another example I can refer to when building my app?

I’m specifically looking for an example that includes Internet Identity and username/password login (like LinkedUp did), so @kpeacock’s To-do example isn’t enough.
