The compatibility issue between Angular version 18.2.0 and bootstrap 5.3.3 is causing functionality errors

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?

Answer №1

After realizing my mistake, I updated the quotation marks in the code from ” to " . This simple change fixed the issue with the button not working and no errors being shown.
