Modern Concurrency Book Server

Book server is not running.

Here is how you reciprocate this error:

swift run

inside 00-book-server folder.

What’s the output of swift --version

swift-driver version: 1.62.15 Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51)

Target: arm64-apple-macosx12.0

Very strange, the only thing that comes to mind to try is delete the build cache first rm -Rf .build and then try to run again. It has happened to me in the past that something’s wrong in the cache and cleaning it resolves build issues

Getting another undefined error:

That’s not an undefined error — the message is that it cannot find github.com

Ah yeah! missed it in writing it out here.
How can I resolve this?

Sorry, I don’t know — maybe it’s an issue with the internet connection.

I checked the internet connection and re-login in my GitHub account.
Somehow I am back to this error only.

Update vapor in Package.swift to a more recent version like 4.68.0.
