Firefox issues with PDFtron WebViewer intialization

[Xavier Hocquet]

Hi there,

We are using the WebViewer successfully in Chrome to do some text searching on PDF documents, however the same code fails on Firefox. This is the setup code (using Webpacker for assets) -

CoreControls.setWorkerPath('/packs/webviewer/core')
    PDFNet.initialize()
      .then(() => PDFNet.addResourceSearchPath('/packs/webviewer'))
      .then(() => {
        setSearchTerms(terms)
        setSearchCount(0)
      })

In Firefox, we get the following error in console -

Unknown action from worker: pdfNetAddResourceSearchPath PDFworker.js:1:13232
Error: Unknown action from worker: pdfNetAddResourceSearchPath

As far as I'm aware, the WebViewer is supported across major browsers. Anything we might be doing wrong?

Thanks,

Xavier Hocquet

You are using WebViewer in full mode and without WebViewer UI? Have you loaded PDFNet.js file?

I'm not the main developer on this side of things so apologies if anything sounds confusing coming from me.

It looks like we are loading both in order to use CoreControls to use some of the searching functionality. We are using the WebViewer UI to display documents. We have the following included in the page -

<script src="/packs/webviewer/core/CoreControls.js"></script>
<script src="/packs/webviewer/core/pdf/PDFNet.js"></script>

And just to reiterate, the same method calls work successfully in Chrome.

Thanks

Xavier
