Sorry, but that's not an environment that we know anything about and thus we cannot provide any help/support for it unfortunately.

PDF.js version

2.11.338

That version is many years out of date, and completely unsupported now.

Steps to reproduce the problem

SetIterator cannot find name did you mean iterator in node_modules/pdfjs-dist/types/web/pdf viewer.d.ts

This sounds like a TypeScript issue, rather than PDF.js one; please ensure that you're using the latest TypeScript version.

I Just recently started getting this error as well. If you find out the cause please share!

You need to update to TypeScript 5.6.

ooof, angular prevents me from going up to 5.6 😞

Same problem here, can't update typescript due to Angular

[calixteman]

We are using the same version as Angular:

• https://github.com/angular/angular/blob/837af44510843b4968977a4cbd12754e21804cb1/package.json#L151

• pdf.js/package.json

  Line 57 in 81cf42d

  "typescript": "^5.6.2",

• https://www.npmjs.com/package/typescript

[nb-midwestern]

That must be for v19. The current version 18 doesn't support it
https://angular.dev/reference/versions
Here is package for Latest angular v18.2.7 https://github.com/angular/angular/blob/46b088a245d19e446624f095d69560b0404270f5/package.json#L150

You can create a .d.ts file with no imports/exports (so that TS considers it to be global), and declare a SetIterator alias for Iterator.

Any guides on how to do that? Facing the same issue using Angular 17 and can't upgrade.

I think:

1. Add e.g. "typings": "./src/typings.d.ts" to your package.json file
2. Create the file src/typings.d.ts containing only: type SetIterator<T> = Iterator<T>;

That worked, you're a life saver!
