Despite my usage of className, I still encounter the error message "Error: Invalid DOM property `class`."

I am having trouble debugging this issue as I am unsure of the exact location of the error. Here is the link to the repository: https://github.com/kstaver/React-Portfolio

Error #2. There are three more promise rejection errors present, which I will address in a separate question.

Warning: Invalid DOM property `class`. Did you mean `className`?

Answer №1

To locate all instances of class=" in your codebase, simply perform a search query within your project. You will likely find numerous occurrences where you mistakenly used className.

These instances can be found in the following files:

  • src/components/Header/index.js
  • src/components/Footer/index.js
  • src/components/Sidebar/index.js
  • src/components/Content/index.js

Answer №2

To make a quick update, simply replace the class= with className=. This can easily be done using VS Code.
