Hello. I get this error on my website when trying to open a PDF, when not logged in.

I have tried versions from 3.17 to 3.22.

" Uncaught Error: Unknown action from worker: undefined at Worker.MessageHandler._onComObjOnMessage (pdf.min.js?ver=3.17.1:22) MessageHandler._onComObjOnMessage @ pdf.min.js?ver=3.17.1:22 "

Hi,

probably different versions of pdf.min.js and pdf.worker.js, outdated cache.
