I found the culprit within my code:
<span>$&nbsp;{{someVariable}}</span>

is unable to be transpiled by ionic, the workaround was:
<span><span>$</span>&nbsp;{{someVariable}}</span>
or
<span>&dollar;&nbsp;{{someVariable}}</span>

During this time I was able to build for specific platforms and the HTML ran fine, this is a bug from that task. It was also very time consuming to track down where the error was happening. It would've been nice to get some type of error or for it to not cause an error to begin with.
