Custom error handling when loading PDFs

[Mirko Lugano]

Hi I'm using (still) WebViewer 5.1.0. Is there a way to custom handle errors occurring when loading pdfs? For instance, I have a .png file which I renamed to .pdf, thus making it an "invalid pdf". When I try to load it with the webViewer I get an error in the console (which is correct): "Uncaught (in promise) PDF header not found. The file is not a valid PDF document."
I would like to be able to intercept such errors and execute my own callback if possible.
I have added 

$(document).on('error', function(e) { //some code })
$(window).on('error', function(e) { //some code })  

in my config.js file but none of that works. Is there a chance to set a custom callback?
Best regards
Mirko

Hi

Would you be able to try this approach? Here:

window.addEventListener('loaderror', function(error) {

  var error = error.detail?.message || error.detail || error.message;

  console.log("Error occured: ", error);//or any message

});
