My Angular project is using version 18.2.0 and Bootstrap was installed with the command: npm install bootstrap
I have updated the "styles array" and "scripts array" in angular.json.
In app.component.html, I added a simple button.
The application was launched using "ng serve".
However, upon opening the browser at http://localhost:4200/, nothing is displayed and an error appears in DevTools: "ERROR InvalidCharacterError: Failed to execute 'setAttribute' on 'Element': 'btn-primary”' is not a valid attribute name."
It seems like Bootstrap is not loading correctly. What could be causing Bootstrap not to load?
