Pdf Viewer ej1 download function not start

Question

I'm trying to use a custom function to download a pdf document.The problem is that when I call the download() function the following error comes out. ej.pdfviewer.min.js
Uncaught TypeError: this._newAnnotationList[(t - 1)] is undefined  The submit function is not called in webapi

I state that this only happens on the production server and does not happen locally.What could it depend on?

I have found that the problem occurs when PDFs have multiple pages and contain forms. So if I manually scroll through all the pages of the PDF, allowing them to be loaded, the download function starts vice versa and goes into error. How can you force the loading of all the pages of the pdf?
