Hi there,

What is the error message you are getting from the response? Are you getting any errors in the console?
Can you share the URL for us to take a look?

Best regards,

Link to document: LINK

Error in console: POST https://api.pdfjs.express/xfdf/merge net::ERR_FAILED 502 (Bad Gateway)

The above error is only when the file size is higher.

Hi there,

This may be due to the complexity of the document itself, when loading this document on pdf.js express, and scrolling to the bottom of the document, this puts a heavy workload on the viewer and results in an error message regarding memory:

So how can this issue be resolved?

We can definitely add this to the backlog to investigate, but we also recommend potentially switching to our new WebViewer-ecommerce platform: WebViewer: JavaScript Document SDK | Apryse
