SAP CPI Odata adapter error 'WstxUnexpectedCharException'

[Muska18]

Hello SAPians,

While trying to connect with S4Hana Public cloud through Sales Order Odata v2 API , I'm getting the WstxUnexpectedCharException error ,attached the image below.

Our odata API url - https://XXXX/sap/opu/odata/sap/API_SALES_ORDER_SRV/A_SalesOrder.

I am stuck here now for a few days trying, googling, checking help documentation, but there is no clear description/explanation available.

Can someone help me here . 

Regards,

Muskan
