Issue with Action Buttons for Purchase Requisition Tasks in SAP Task Center Integration

Hi,

We are currently configuring the integration between SAP Task Center and SAP S/4HANA to enable the approval and rejection of Purchase Requisition tasks through SAP Mobile Start.

At this stage, the tasks and their details are being successfully retrieved by Task Center. However, we are facing an issue where the “Accept” and “Reject” action buttons are not functioning properly, preventing users from completing the approval process.

The buttons don't show any letter and have different message errors when clicked.

When clicking the supposed Accept or Reject buttons (Which are only red or green with no text) it says that 0 is selected, indepentendly of which button is chosen.

When "Submit" is clicked the next error is presented:

Solic. pedido 10253459 00010

There was an error while processing request for task operation. Unexpected character ('<' (code 60)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false') at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 1, column: 1] Try to perform the action again. If the error persists, contact the system administrator.
