The problem occurs when you create a global variable with an object of any class, except that it handles the variables only to an array, but when it receives an exception in the global variable, it throws an internal error.
It is easy to see that first the exception is normally worked out, and then it is covered by a mistake from the exception itself, and in this case the error is only visible in the log
