Chart.js not deploying properly on Heroku

I have been using angular-chart.js with my app locally and I have not had a problem. However, when I deploy my app on Heroku, I my page breaks because it Chart.js is not deployed properly.

Uncaught SyntaxError: Unexpected token < Chart.min.js:1

Uncaught ReferenceError: Chart is not defined angular-chart.min.js:1

Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.4.6/$injector/modulerr?p0=swellsApp&p1=Error%…swells.herokuapp.com%2Fassets%2Flibs%2Fangular%2Fangular.min.js%3A19%3A463) angular.min.js:38

I don't get these error when I run it on my local server. I'm sourcing the scripts properly and have included my dependencies in my app as well. What I don't understand is that my other scripts have been loading with no problem. It's just Chart.js that is giving me the issue...

Any thoughts???

What I see under Resources in Chrome's DevTools

Check your angular.json file for Chart.min.js and change both instances to all lowercase. Heroku is case sensitive.

Worked for me using Angular 13.

I found an alternate solution to this problem. I sourced a CDN for Chart.js and that worked. It seems that Chart.js was deploying with my app for some reason so I decided to source it from a cdn and that did the trick

 <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.min.js"></script>

I ahve that error when I have a mistake on the src property of my libs.

check that this line is ok:

<script src="assets/libs/angular-chart.js/dist/angular-chart.min.js"></script>

Maybe you misspell the src path.

What about if you change to this <script src="assets/libs/angular-chart/dist/angular-chart.min.js"></script> I think that angular-chart.js is not the name of the folder
