There are some possible reasons why you are getting this error. Here are some of them:

You have not initialized or assigned a value to the String object that you are calling the equalsIgnoreCase method on. [Make sure that you have given a valid value to the String object before using it]
You have passed a null value as an argument to the equalsIgnoreCase method. [Make sure that the argument that you are passing to the method is not null
You have received a null value from a method or a database query that returns a String object. [Make sure that you check the return value of the method or the query before using it
I hope these possible reasons help you find and fix your error.
