call flexmonster-data-server.exe server from react native app

Hello guys,
i am in the process of evaluating the control and I am trying to populate the grid in the React app with some data from mssql. First, here is how I update the flexmosnter-config.json:
{
"DataSources": [
{
"Type": "database",
"DatabaseType": "mssql",
"ConnectionString": "Server=mydb;Uid=username;Pwd=password;Database=TestDB",
"Indexes": {
"TestDB": {
"Query": "SELECT * FROM TestTable;"
}
}
}
],
"Security":
{
"Authorization":
{
"Enabled": false
},
"CORS":
{
"AllowOrigin": "*"
}
},
"DataStorageOptions":
{
"DataRefreshTime": "60"
},
"Port": "9500"
}
 
when i run the exe, i get this:
2020-05-22 15:19:06.4003|INFO|Flexmonster.DataServer.Core.PrepopulatingCacheService|Start loading index TestDB
2020-05-22 15:19:06.7212|INFO|Flexmonster.DataServer.Core.PrepopulatingCacheService|Index TestDB was loaded in 0.31771 seconds
2020-05-22 15:19:06.7212|INFO|Flexmonster.DataServer.Core.PrepopulatingCacheService|Prepopulating finished. Total time spent: 0.31771 seconds
2020-05-22 15:19:06.7800|INFO|Microsoft.Hosting.Lifetime|Now listening on: http://[::]:9500
 
it seems wrong, that it doesn't even say "http://localhost:9500"
 
And in the React app i tried this:

 <FlexmonsterReact.Pivot         
         report = {
            dataSource: {
                type: "api",
                url: "http://localhost:9500",
                index: "TestDB"
            }
            }
         toolbar={true}
        />

 
And it doesnt work. Can someone help me out? Thank you in advance.
