Error in Employee Profile MSS based on SAPUI5

Hi experts,

when i call the URL /sap/bc/ui5_ui5/sap/HRESS_EMP_PRO_G/index.html, i can see the employee profile without any problems. But if i start this application over the MSS Chip "My Team" with a specific employee, i just get a gray page without any content. When i look into my browser console, i can two JavaScript errors (see attachment).

The error-text of the odata Service is: In the context of Data Services an unknown internal server error occurred

So it looks like, that the following URL causes some problems in the backend logic:

/sap/bc/ui5_ui5/sap/HRESS_EMP_PRO_G/index.html?MEM_ID=556341843

Any ideas?

Regards

Michael
