PDF.js version: 2.6.347

First of all, that version is no longer supported; please find the latest releases at https://mozilla.github.io/pdf.js/getting_started/#download. Hence you'll need to update to either version 2.7.570 or 2.8.335.

Depending on which of the two versions you pick, please note:

• https://www.npmjs.com/package/pdfjs-dist/v/2.7.570?activeTab=readme

  For usage with older browsers or environments, without support for modern features such as e.g. async/await, ReadableStream, optional chaining, and nullish coalescing; please see the es5 folder.

• https://www.npmjs.com/package/pdfjs-dist/v/2.8.335?activeTab=readme

  For usage with older browsers or environments, without support for modern features such as e.g. async/await, ReadableStream, optional chaining, and nullish coalescing; please see the legacy folder.

Sorry to bother you, both version 2.7.570 and 2.8.335 get the same error: annotationStorage: annotationStorage?.serializable || null
Please check it again. @Snuffleupagus

This clearly suggests that you didn't actually read/follow all of #13190 (comment), since the quotes (from the relevant READMEs) explain what you need to do here.

See:

Optional chaining (?.) https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining

Once more: The answer was already provided in #13190 (comment), and it means that you'll need to import from node_modules/pdfjs-dist/es5/build/pdf.js[1] instead.

[1] Or node_modules/pdfjs-dist/legacy/build/pdf.js, when using PDF.js version 2.8.335 and above.

@Snuffleupagus This import doesn't work for me. Folder 'es5' not exists in node_modules
