Cannot read properties of undefined (reading 'numPages')

[Chieleman]

In my application a user can quickly loop through pdf's using a button. Unfortunately, if the users clicks to fast, PDFJS throws errors...

(Sometimes an other error pops up: 'Uncaught (in promise) Error: Worker was terminated' or 'Error: Uncaught (in promise): Error: Transport destroyed')

I made a stack blitz to demonstrate the problem.

I wonder if there is a work around for the problem demonstrated. e.g. suspend the worker or cancel previous load action
