Having done a stack trace I can now see that the moddle extensions that I manually load are now coming into the package array as “module” and that the prefix field is not being found by registry.js in this specific call:
ensureAvailable(pkgMap, pkg, 'prefix')
As a result, the prefix shows as “undefined” and, therefore, only one of the two moddle extensions will load. I assume that this is caused by a Webpack upgrade, but I’m really not a javascript expert and have no clue how to fix it. I took a screenshot of the variables in scope. Attached.
