Issues with modals appearing improperly after transitioning to NG-Bootstrap 15 and Bootstrap 5 upgrade

UPDATED following a thorough examination:

In the process of upgrading our application from NG-Boostrap v11 with bootstrap 4 to NG-Boostrap v15 with Bootstrap 5 and Popper, we also made the switch from Angular 15 to Angular 16. Despite successfully resolving numerous breaking changes associated with the bootstrap update, we are facing an issue where all Bootstrap variables are returning as undefined.

We have ensured that all necessary SCSS files are imported correctly and our configurations appear to be in order after utilizing "ng add @ng-bootstrap/ng-bootstrap" for setup. However, the persistent problem remains with the variables displaying as undefined.

It is important to mention that the CSS files compile without any errors, yet the variables persist as undefined within the browser.

Answer №1

After some thorough investigation, the root of the problem has been uncovered. The culprit turned out to be the css-vars-ponyfill tool that we were utilizing to cater to outdated browsers. By removing this component, all functionality has been restored and everything is now back in working order. This information is being shared here for the benefit of anyone who may encounter a similar issue in the future.
