Construct Filter with Javascript function

This is now working for operators besides "In". Modified code: 

function advancedFilter(table, column, logicalOperator, operator, value){
    
 if (logicalOperator == undefined || logicalOperator == "" || logicalOperator == null) {
 logicalOperator = "And";
 }
 if (operator == undefined || operator == "" || operator == null) {
 operator = "Is";
 }
 if (value == undefined || value == "" || value == null) {
 value = 0;
 }

    if (operator == "In") {
        return filter = {
            $schema: "http://powerbi.com/product/schema#advanced",
            target: {
                table: table,
                column: column
            },
            logicalOperator: logicalOperator,
            conditions: [
                {
                    operator: operator,
                    values: value
                }
            ]
        };
    }
    else {
        return filter = {
            $schema: "http://powerbi.com/product/schema#advanced",
            target: {
                table: table,
                column: column
            },
            logicalOperator: logicalOperator,
            conditions: [
                {
                    operator: operator,
                    value: value
                }
            ]
        };
    }
    
}

Called in the view: 

var arr = [104, 102, 117];
var useFilter = advancedFilter(table, column, "", "In", arr);

Pushed to the report filters:

                report.on('loaded', event => {
                    report.getFilters()
                    .then(filters => {
                        filters.push(useFilter);
                        return report.setFilters(filters);
                    })
                })

It may also be worth noting that I have the function in a separate javascript file that I am referencing in the view. Here is what returns in the alert text box: 

{  
   "$schema":"http://powerbi.com/product/schema#advanced",
   "target":{  
      "table":"SiteInfo",
      "column":"SiteId"
   },
   "logicalOperator":"And",
   "conditions":[  
      {  
         "operator":"In",
         "values":[  
            104,
            102,
            117
         ]
      }
   ]
}

I still get the error message in the developer console on the web page: Uncaught (in promise): Array[4].
