Hey there, on a specific page in our app, when loading another page, this error appears in xcode and the webview reolads completly (sometimes it works?).

If don’t know how to dig into this, does someone experienced the same and can help me getting in the right direction?

Also if some of the Ionic team would like to help, please answer me, i will give you access to the app so you can debug i for example?

Hey EinfachHans, finally managed to fix ?

Any particular component to mention on the page where it was crashing ?
