2932437 - "PKIX path building failed" when creating a Model based on a Live Data Connection to SAP Universe in SAP Analytics Cloud (SAC) & SAP Digital Boardroom


This KBA relates to the legacy version LUC 2.x only. It is heavily recommended to upgrade to LUC 3.x for Full Support and for a much simpler deployment process.

When attempting to create a model based on a Live Data Connection to SAP Universe using Live Universe Connector 2.4, the Query Builder is empty, and the following error occurs in SAP Analytics Cloud (SAC):

  • "{"code":500,"message":" SSLHandshakeException invoking https:/<tomcathostname:tomcatport>/biprws/raylight/v1/universes/27532: PKIX path building failed: unable to find valid certification path to requested target","stacktrace":" SSLHandshakeException invoking https:/<tomcathostname:tomcatport>/biprws/raylight/v1/universes/27532"

  • HTTPS BIPRWS hostname and port has been defined in the file


  • SAP Analytics Cloud (Enterprise) 2020.8.9
  • SAP Live Universe Connector (BOE Live Data Connect) 2.4
  • SAP Business Intellligence Platform 4.2 

Reproducing the Issue

  1. Login to SAP Analytics Cloud
  2. Create a Live Data Connection to SAP Universe (Successful)
  3. Create a Model using same Connection
  4. Observe Query Buildler is empty and error message is displayed 


This issue is currently under investigation by development.



  • As a workaround, please use the BIPRWS Port for HTTP and declare these changes in the boe.restUrl parameter in the file
