NodeJS - Docker - Bootstrap issue

Hi,

I’m trying to build an app using NodeJS, just testing things out, but I seem to be running into an issue with displaying pages with Bootstrap styling.

If I add any Bootstrap element to a page it shows in Wappler fine but when saved and viewed in the browser there is no Bootstrap styling it’s just plain text.

I’m running Wappler Version 3.9.7 (3.9.7)
NodeJS
Docker Desktop
on a MAC
The screenshot shows the problem.

Am I missing something?
