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

Check the logs to see the URL that is being invoked because it indicates an incorrect & character at position 128.

Have you solved this? if yes, please let me know wat u did?

You have to create a communication user and use that for the integration. You can find several resources in the community and in other SAP assets for this.

Is this confirmed to be the issue? I am getting the same error in a different scenario but I am having the authentication working.

The error is becasue the response is not valid xml. The usual cause is authentication failure. In this case the response code is 200 with html content.
