<p>I deployed my angular application(Static webpage) on kubernetes and tried launching it from Google Chrome. I see app is loading, however there is nothing displayed on the browser. Upon checking on browser console , I could see this error</p>
<p>&quot;Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of &quot;text/html&quot;. Strict MIME type checking is enforced for module scripts per HTML spec.&quot;
for (main.js,poylfill.js,runtime.js) files . I research few forums and one possible rootcause could because of <code>type</code> attribute in <code>&lt;script&gt;</code> tag should be type=text/javascript instead of <code>type=module</code> in my index.html file that is produced under dist folder after executing ng build. I don't how to make that change as to these tags as generated during the build process, and my ng-build command is taken care by a docker command.</p>
<p>URL i'm trying to access will be something like : &quot;http://xxxx:portnum/issuertcoetools</p>
<p>note: The host <code>xxxx:portnum</code> will be used by many other apps as well.</p>
<p>Are there any work-arounds or solutions to this issue?</p>
<p>index.html - produced after running ng-build in local, (which is the same i see in kubernetes POD too)</p>

<p>This error usually happens because you deployment was into a subfolder, so it seems like Angular is fetching you app directly from your base URL, so your html is found when you go to your <code>domain.com/mysubfolder/index.html</code>, but as the Angular fetches your resources from <code>domain.com/index.html</code> instead of domain.com/mysubfolder/index.html; I’m pretty sure this is the cause of your issue. You can resolve it building your app with:</p>
<pre><code>ng build --prod --base-href mysubfolder
</code></pre>
