PDF.JS viewer Error 500

Describe the issue or problem
Dear community, I am receiving error 500 when the PDF button is pressed in any magazine article, I checked all the configuration and everything is correct. PDF attachments load perfectly. If I disable the PDF.JS Viewer plugin, when I click on the PDF button, it downloads the file correctly.

What application are you using?
Currently using OJS 3.3.0-17
