Was able to resolve my issue by removing the “^” from the versions of AngularJS. Apparently what AngularJS feels is “compatible” (v1.7.5) with version 1.5.5 simply is not compatible. Largely due to the ngSanitize changes that were introduced in v1.6.4. Thankfully I was able to locate the ngSanitize code, and locate the non-minified area of code that looked to minify to the “a(r[t])” was in fact “lowercase(items[i])”. This gave me something to go on since ngSanitize seems to be a headache for many other folks in this set of versions too.
Hopefully this can serve as a pointer for other folks that try to simply build the openmrs-owa-generator and see errors right off the bat. I’ll see about adding a PR to the generator code base if time allows.
