Hi @MichaelL,

Thanks for reaching out! Can you share a sample of your code that is throwing this error? I’m not able to reproduce this error in our WebViewer Demo or using WebViewer Server.

I’m just trying to use the getDocumentViewers() method in our application, as shown in the guide PDFTron Systems Inc. | Documentation

Relevant code in our application :

            const [documentViewer1, documentViewer2] = Core.getDocumentViewers();

it throws a typescript error on compiling because the method doesnt exist in type.d.ts

When using ts-ignore, in case the type.d.ts file was not updated

// @ts-ignore
const [documentViewer1, documentViewer2] = Core.getDocumentViewers();

we have an error when the method is fired in the browser.

main.js:1 ERROR Error: Uncaught (in promise): TypeError: Cannot read properties of undefined (reading ‘getDocumentViewers’)

I don’t know what you mean by reproducing with the webviewer server demo or server. I checked the 8.9 sample code and nowhere is this method used in the samples.

Addendum :
the getDocumentViewers mentionned in the guide doesnt even exist in the API that is being referenced in the same guide

Hi @MichaelL,

I appreciate your patience and thanks for bringing it to our attention. I’ve informed the team and will work on getting the documentation updated to fix the Typescript error.

Let me know if you have any other questions.

Thanks Adam

In the meantime, using @ts-ignore does the trick.

Hi @MichaelL,

The documentation should be updated now in our latest nightly stable build for 8.9. You can find it
in our nightly stable installation page, or install via npm.

Let me know if you still have issues.
