File Listener is throwing errors in the log



Post upgrade to Pega 7.2.2, the File Listener generates errors in the log files.

Error Messages InvalidParameter Class not defined in dictionary: Rule-Service-null aClassName .createPage

Caught throwable processing some_file_name.xml PRException

Caused by: Authorization failed, please contact system administrator.

Steps to Reproduce

  1. Create a File Listener.
  2. At runtime, test the File Listener with 200 to 500 files.

Root Cause

A defect in Pegasystems’ code or rules.

When authentication is enabled for the File Listener, the ServiceAPI.setRequestorPrivileges() method is invoked where the Service Type is not set. Hence, the class formed is RULE-Service-null, which causes the issue. 

The defect exists in the below files:
  • com/pega/pegarules/integration/engine/internal/services/
  • com/pega/pegarules/integration/engine/internal/services/file/
  • com/pega/pegarules/integration/engine/internal/services/file/


Apply HFix-33841.
