Cordova keychain plugin does not support on iOS12 an later

getting below error for setJson/set on keychain methods -

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull boolValue]: unrecognized selector sent to instance 0x111f02f08'

Did you find a solution for this?

Yes, there were silly mistake of not sending required parameters to the plugin.
