Error: I have a valid license key but i still have errors

Which product are you using?
PDF.js Express Viewer

PDF.js Express Version 8.7.0

Detailed description of issue
Hello,

I have a valid license key associated with my account, and it matches the one used in my project. However, the viewer has suddenly stopped working, even though I haven’t made any changes to the PDF.js Express implementation.

I am now receiving the following error message:

“A valid license key is required to use the view-only build of PDF.js Express. Get your free license key at PDF.js Express (account required).”

Expected behaviour
At the start it was working.

Hello Alex,

Could you provide the full license key you are using? You can send it to darian.chen@apryse.com. Are there any other console or network errors? Please also provide the code snippet for the constructor showing how you are passing the license key.
