Error Messages

Not Applicable

Steps to Reproduce

 

1. Create a test activity.
2. Set the test activity to send message body.
3. Call the REST service.

Root Cause

A defect in Pegasystems’ code or rules

This version of Pega (Pega 7.1.9) does not support binary request bodies as a Pega-provided feature. Support for binary request bodies was made available in Pega 7.3 for POST and in Pega 8.1 for all HTTP verbs.

Resolution

Best practice: Update or upgrade to the latest Pega Platform release, including the latest Pega Platform Patch Release.

Alternative
If you cannot update or update your deployment of Pega, perform the following local-change:
In Step 5 of the activity pyInvokeRESTConnector, update the mData setting as shown in the following code snippet:

//mData = messageData.getBytes(); --> Old code
mData = Base64Util.decodeToByteArray(messageData); --> Updated code
