Hello suporte,

Apologies for the delay. I was able to get it working with this code:

 data.append('xfdf', xfdf);
    await fetch('https://api.dattasign.com.br/api/file_view').then( async (resp) => {
      data.append('file', await resp.blob())
      const response = await fetch('https://api.pdfjs.express/xfdf/merge',
        {
          method: 'post',
          body: data
        }).then(resp => resp.json());
  
      const { url, key, id } = response;

After converting the response to a blob it worked.

Hello @tgordon,

We did test this solution, but did not work.

The problem isnt the File, the problem is the XFDF is larger than the size that HTTP allows

XFDF follows:

@tgordon Hello mate, sorry for disturbing, any news about this?

Hello suporte,

Apologies for the late reply, we have been experimenting to see if we could get this large XFDF to merge in the API. I think the limitation of the HTTP size results in this merge to be impossible. I tried posting the XFDF to a secret GitHub gist and fetching it, then fetching the file, then putting those blobs into the merge API however it still resulted in a 413 error.

I think the workaround here would be to export the annotations in chunks, say you have 10000 annotations, you would export 1000 at a time, then make multiple calls to merge them.

I have attached the code I have been testing with, that includes the XFDF GitHub gist link

Hello, @tgordon!

You PDF.js Express team could do for xfdf as you already do for the file process. For example, for xfdf larger than 5.5mb, it would send the xfdf via URL.

What do you think of this update?

Best regards,
Vicente!

Hello vicente,

We don’t currently have this on our roadmap but we will add it to the backlog for our product team to review.
