pdfjs-dist | Generic build of PDF.js library | Runtime Evironment library

I am trying to use the persistent build cache feature provided by angular but look like its not working for me, I am trying the below command

I am trying to follow the documentation for pdfjs found here https://www.pdftron.com/documentation/core/guides/features/manipulation/remove/ in an attempt to remove a page from a PDF I have uploaded to my html page. Here is my html code:

I'm trying to start working on an Angular project in my Ubuntu 18.04 system, but the npm i command fails after printing the following:

SOLUTION: To make the HTML code work, swap "reader.readAsText" for "reader.readAsBinaryString" as explained in @KJ's answer

I am trying to view a PDF using PDFJS. I have the following code which works fine for a demo PDF I got from the PDFJS website, however it doesn't work for other PDFs I have tried. Here is the raw text of the demo PDF that works:

We recently migrated our app to Angular 10 and PrimeNG 9, and now we are preparing to migrate these frameworks to the latest version.

We trying to prepare our app to migration and want to use Ivy Compiler as Angular recommends.

But when activate Ivy compiler and aot to true it shows the following error when do ng build:

ERROR in node_modules/@maestro-ng/primeng/maestro-primeng.module.d.ts:1:22 - error NG6003: Appears in the NgModule.exports of AppSharedModule, but could not be resolved to an NgModule, Component, Directive, or Pipe class.

This likely means that the library (@maestro-ng/primeng) which declares MaestroPrimengModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

This is the complete package.json:

This exception is returning on almost on every file, only one works for me From console, it also returns:

Warning: Indexing all PDF objects.

Right after the splash screen fades out, the app is stuck on a blank page leaving this error in the console (ProxyWeb::didFailProvisionalLoadForFrame)

Note that the same app works perfectly on all previous IOS versions. I tried to change the webview plugin version, cordova-ios, and played around with angular build process but no luck.

I suspect that the angular portion of the project does not initialize, cordova itself loads successfully but anything beyond that is just an empty blank screen.

I can't do "npm install" on this project anymore and I don't know why because I'm a novice. I see in the picture top that something about "node-sass" maybe is the problem. Should I update node-sass? I must ask so I don't cause more trouble

package.json

After do a git clone im getting this error with my project after npm install:
