Module is not defined

[Psichorex]

Hi I am using Shepherd.js 12.0.2 recently tried to upgrade from 11.2.0.
I use Shepherd in an ASP.net project and shepherd is downloaded into the node_modules and then injected via ResourceManagement.

Since I updated the version I get the following error:

The error originates from this line:

Biggest difference I have seen is that in 12.0.2 there is no longer a shepherd.min.js which we also included before in the 11.2.0 version.

The shepherd.js script is indeed added to my footer section:

Perhabs I am missing a dependency?

I also try to add Shepherd as <script src="/Lombiq.Walkthroughs/shepherd.js/js/shepherd.mjs" type="module"></script> but Shepherd is still not available under the global window, it is undefined. So my probelm originates from Shepherd being undefined when it is being referenced.
