@uzi the onUncaughtException is a handler that comes from chromium, and we just expose it through our API. Due to this fact, there is nothing that we can do as It should be handled on the Chromium side.
Anyway, I will discuss it more internally to check if there is more info.
Added function namespace for error, when trying to execute an API function with wrong parameters: Wrong parameter type in position 2. Should be int. value double
Added 4th param to overwolf.extensions.onUncaughtException - with all exception data available.
