Warnings after upgrading to version 8

Product: Webviewer

Product Version: 8.0.0

Please give a brief summary of your issue:
Warning after upgrading to 8.0.0

Please describe your issue and provide steps to reproduce it:
I just upgrade from 7.0.3 to 8 version and I am getting this 2 warnings, not sure why.

I downloaded it yesterday.

webviewer-ui.min.js:68 react-i18next:: It seems you are still using the old wait option, you may migrate to the new useSuspense behaviour.

webviewer-core.min.js:189 Cannot cancel callback [object Object]

Any idea why?

I would like to report that version 7.3.3 of the webviewer also exhibits this problem

Hi Ana,

Thank you for bringing this to our attention. These items are currently on our backlog, and we will hopefully get to them soon. As a reminder, these are warning and do not affect the execution/performance of the WebViewer. If you stay up to date with your WebViewer version, we will hopefully have these warnings resolved in a future release.


I am also getting this warnings on webviewer version 8.1.0.

Hi Ana,

Thank you for notifying us of the status of this issue in 8.1. This issue is still on our backlog, and we have been looking into it. Unfortunately, because these are warnings and do not affect the execution/performance of the WebViewer, they are not a very high priority for our team currently. We will continue to do our best to figure out a solution, but we appreciate you reaching out to us in the meantime.


Just for your information,
the problem is still persist in Version 8.8.0


It is still the same, my annotation to a specific page is falling back on the first page. Even though warning it is causing issues.
