Getting CORS Error while calling Northwind Service

[Yash_Sharma]

Hi Experts,

I am facing problem of getting CORS error while calling Northwind oData Service to show data in my SAPUI5 Application created in BAS.
I am using 2 approaches here:
1. By Using the Rest API

  By directly calling the Service URL through ODataModel, I am getting CORS error on this but while disabling the browser security I am getting the data perfectly. 

2. By Configuring the  Northwind Service to the Destination in BTP and try using the destination.

manifest.json

xs-app.json

since the preload is true, the destination is loading first to fetch the metadata,

I am getting this:

Please help me with this.

Hi,

1- direct url wont work here, and also if you use http://services.odata.org in your destination then also it will give CORS issue.

2- this is fine just you need to remove destination name from the uri in manifest file, it should be like below,

"dataSources": {
    "mainService": {
        "uri": "/V2/Northwind/Northwind.svc/",
        "type": "OData",
        "settings": {
            "annotations": [],
            "localUri": "localService/metadata.xml",
            "odataVersion": "2.0"
        }
    }
}

hope this helps.
