Getting error: RuntimeError: unreachable

Bug Reports
1

I have one user who is reporting occasionally getting this error. I haven’t been able to reproduce it on any other computer but it crashes the whole PDF display. The user is using Chrome 85 (32 bit) on a Windows 7 computer. Maybe you can give some insight into what is happening and what triggers this?

Hello pearl,

Unfortunately it’s difficult to investigate further without being able to reproduce the issue on our side. Would you be able to provide some steps that we can take to reproduce the issue? A sample project could be useful as it may be something in your customized code that is causing the issue.

Does this happen with specific PDFs?

Best regards,
