I'm running into this special error message while trying to build a simple NextJS application (using npm run build):

I don't know who codemirror is, or why it's not letting me build my project. From reading around I gather that this issue occurs with NextJS when trying to build a project on the server side instead of the client side, because the project does not have access to a window or navigator. In that case, what should I do? The tutorial I'm following seems to breeze through this step just fine, so should I just look at their package.json and downgrade all of my packages? Any advice would be appreciated.
The error was with my import of import SimpleMDE from "react-simplemde-editor" (located in create-post.js of the repo link above).
I implemented the solution proposed by modikum here: https://github.com/dabit3/next.js-amplify-workshop/issues/21.
Now the project builds successfully.
