Getting got unexpected undefined error while changing redux state

[gani419]

I'm trying to change the state of redux state.
state is a boolean value. So making initial value to false.
Even though when I try to update the redux state giving the above error. (Mainly when I make it to false).
Working fine in android but giving the error in ios.
