Set custom filter values as 'blank' or null

Thanks for reply,

You have suggest me use advance filter for handling null value but

Actually my implementation is like I have one custom filter which will I want apply to existing filter(not change any existing filter).

So that time whenever I will try following code it will not work

var basicFilter = {
$schema: "http://powerbi.com/product/schema#basic",
target: {
table: table,
column: column
},
operator: 'In',
values: [value]
};

CurrentPage.getFilters().then(function (allTargetFilters) {
allTargetFilters.push(basicFilter);
CurrentPage.setFilters(allTargetFilters);
});

at time of setFilters it will throws error becuase 

In that existing filter there is one basic filter

{
$schema: "http://powerbi.com/product/schema#basic",
target: {
table: table,
column: column
},
operator: 'NotIn',
values: [null]
};  

so due to null value it will throws error,So my question is how to handle this null value such that it will not throws error.
