Hi,
For me it is resolved by upgrading the Modules.
After upgrade to Mx10.24, check your Native Mobile Resources and Nanoflow commons are upgraded.
and then Download the latest version of Signature widget - V 1.0.8 · Highest Compatible Release with Studio Pro 10.24.16
If you look at this GitHub issue — https://github.com/react-native-webview/react-native-webview/issues/2648 — You can see that it often indicates a missing or incompatible module (or a version mismatch). Based on that, I would first check the dependencies of this module and make sure you have the correct versions installed and updated. If you haven’t done that yet, updating this module and its dependencies is the first thing I would recommend.
Installing the previous version of the widget did it. The new widget can't be used in Native apps...
