My project was working with angular 11 and bootstrap v3 but since I updated angular to v13 my ruby project although building spits out runtime ActionView:Template errors such as:
actionview (6.1.4) lib/action_view/template.rb, line 314
which tells me that the (compile &) render template method in ruby is tripping an error.
FYI the compatibility table from:
https://www.npmjs.com/package/ngx-bootstrap#compatibility
goes as far as: Angular 10 with Bootstrap v3
