Getting a blank meta box when both Classic Editor plugin and OneSignal Push Notifications plugins are activated.

Getting the following console errors:

The meta box works fine when using Gutenberg and OneSignal Push notifications. Issue only happens when using the Classic Editor plugin and OneSignal Push notifications.
I expect the meta box to show up.

Probably a bug with the latest version of OneSignal as seen here:
https://wordpress.org/support/topic/help-with-fatal-error-uncaught-error/
Author has a patch in their repo, but not reachable for me.
Issue on their GH repo: https://github.com/OneSignal/OneSignal-WordPress-Plugin/issues/173
I confirm that, disabling OneSignal plugin, all is ok again.

I just updated , but it didn't work at all , Problem persist
Can you please hard-refresh? This clears the cache and reloads the JS file
Empty Yoast Seo sections if using Classic Editor Plugin

Is the same console error specified in the main post of this thread.
Please inform the customer of conversation # 483487 when this conversation has been closed.
After hard refresh it seems to work as usual.

For me Hard refresh , Drop Cache from Server , Cloudflare purge, and I keep getting the same error .

@LockeAG have the line-numbers changed from OP's original screenshot? In other words, are you still getting the same error even with the reloaded code? If you can include the full stack-trace or screenshot similar to OP's, we would be much better able to know what's going on and assist you. Thanks

Sure :

Yeah, it looks like your browser is caching the previous version. Please make sure to do a hard-refresh ("force-reload") or clear your browser's cache. Another way to verify is by opening up a different profile in your browser or trying on another browser altogether (Safari, Chrome, Firefox). You can find more info here: https://wordpress.org/support/topic/version-1-16-16-thread/

This should be closed as the OneSignal 1.16.16 release has fixed it, remind all users to clear local browser cache.
Closing as this is fixed as mentioned above by Jeroen
