Power BI Report level Filters not working properly in ASP.NET MVC application

Hi All,

My ASP.NET MVC application's URL use three parameters, that is Region, Subregion and Pagenumber from Power BI basic filter. When I run application which gives right results for Region and Pagenumber, but nothing showing for Subregion. My code has given below. I can't figure it out what is wrong here. Help will be appreciated

// for region ,subregion and page level filtering
for (var i = 0; i < hashes.length; i++) {

hash = hashes[i].split('=');
if (hash[0] == "region") {
region.push(hash[1]);
}

if (hash[0] == "subregion") {
subRegion.push(hash[1]);
}

if (hash[0] == "page") {
defaultPage = "ReportSection" + hash[1];
}
}

if (region[0] == undefined) {
region = [];
region.push("VNW","VMP","VGW","VGN","VGE","SOA","QLD","Other","Office","NSW","Display");
}

if (subRegion[0] == undefined) {
subRegion = [];
subRegion.push("VNW","VMW","VMP","VMN","VME","VIC","VCW","VCS","VCN","SOA","QLD","Other","NSW","Display");
}
const filterRegion = {
$schema: "http://powerbi.com/product/schema#basic",
target: {
table: "Region Lookup",
column: "Region"
},
operator: "In",
values: region
};

const filterSubRegion = {
$schema: "http://powerbi.com/product/schema#basic",
target: {
table: "Sub Region Lookup",
column: "Sub Region"
},
operator: "In",
values: subRegion

};

var config = {
type: 'report',
tokenType: models.TokenType.Embed,

embedUrl: embedUrl,

permissions: models.Permissions.All,
settings: {

},
pageName: defaultPage,
filters: [filterRegion, filterSubRegion]
};
// Get a reference to the embedded report HTML element
var reportContainer = $('#reportContainer')[0];
// Embed the report and display it within the div container.
var report = powerbi.embed(reportContainer, config)

Thank You
