OIC SOAP Connection — OAuth Authentication Fails Intermittently

Summary:


Content (please ensure you mask any confidential information):

Hi everyone,

We configured a SOAP connection in Oracle Integration Cloud (OIC) using OAuth authentication. However, when we run our integrations, the SOAP invocation fails intermittently.

  • Some integration iterations fail.
  • Most iterations succeed.
  • Sometimes, all iterations complete successfully without any issues.
  • When we change the SOAP connection authentication from OAuth to Basic Authentication, the integration works consistently without any failures.

Error msg:

CASDK-0033: Received a SOAP fault while invoking endpoint target: https://XXXXXXX-test.fa.ocs.oraclecloud.com:443/xmlpserver/services/ExternalReportWSSServi…. This indicates a processing exception on the service endpoint side. Please check service side logs to further diagnose the problem <![CDATA[ Fault Code : env:Receiver Fault Reason : java.lang.RuntimeException: Failed to retrieve data from Presentation ServerCould not connect to OBI Presentation Service ]]>

Howdy, Stranger!
