Error when deployed (possibly due to minification)

[dancherb]

Issue Description

When the project is built and deployed on Heroku, the following error appears. This error does not appear when using the standard face-api.js npm package:
Uncaught SyntaxError: Invalid left-hand side expression in postfix operation

This references the following minified code:
async nextState(e){await e;let t=await wF(this.iterators,function(e){return e instanceof wJ?{value:e.next().then(e=>(0++,e.done&&0++,e.value)),recurse:!1}:{value:null,recurse:!0}});

It seems that "0++" is causing the issue here. This appears to be minified from the following function in @tensorflow\tfjs\node_modules\@tensorflow\tfjs-data\src\iterators\lazy_iterator.ts. It appears that the variables numIterators and iteratorsDone are reduced to simply 0, thus giving the code 0++.

let numIterators = 0;
 let iteratorsDone = 0;
 
 function getNext(container: IteratorContainer): DeepMapAsyncResult {
   if (container instanceof LazyIterator) {
     const result = container.next();
     return {
       value: result.then(x => {
         numIterators++;
         if (x.done) {
           iteratorsDone++;
         }
         return x.value;
       }),
       recurse: false
     };
   } else {
     return {value: null, recurse: true};
   }
 }
