| Chapters 4 & 5 Code samples - Router.js, Profile.js |
Listed as 'minor technical' because this is probably because the libraries have evolved since publication however the code from both online and github repo seem to need updating. This is for Chapters 4 and 5. |

| Chapter 6 Adding the Custom Logic for Resizing the Image |
Installing the sharp image library doesn't work. The probelm is that the version is now too old to install without the target flag (which was used earlier as I see in errata). According to the comment that I linked the version should be v0.25.0+. But right now it's 0.23.2. I fixed this by changing it to 0.25.4 and the amplify push worked. |

| Chapter 4 & 5 Protected Component & Creating the protectedRoute Hook |
There's a problem with the protected route. The authorization is done in the useEffect hook so it applies after the page is rendered. So the user can slow down the internet connection etc. and see the content on the protected page for a short time before redirecting. So it isn't actually protected. |
