Same problem here, in my case, using angular 16.2.12 :

• error appears in every version since 10.1.0
• used many ng2-pdf-viewer and pdfjs-dist version combinations does not seem to work either

The only solution that i have found to use it with angular 16 is downgrade to 10.0.0 and remove pdfjs-dist from package.json

On an angular 16 project, try adding;

"skipLibCheck": true,

to your tsconfig.json file.

This has fixed the issue for me on my angular 16 project.

On my Angular 17 project I found this was not necessary.

I noticed in this commit 15cba0d that the same was added to this project.

Si bien funciona utilizar

"skipLibCheck": true

no me parece la solucion correcta.
