Hello! while working with a private Pega laboratory environment, we identified a problem during the Knowledge Buddy ingestion process. After reviewing the configuration and execution flow, it appears that the issue is related to the authentication token generation for the Vector Store service.
The activity “GetVectorStoreConnectionSettings” (Class: PegaFW-QnA-Data-VectorSvc-Config) tries to obtain the authentication token using the following Java code:
SAXToken = com.pega.fnx.textservice.http.client.JwtTokenGenerator.get().getToken();
However, the token is not generated, and the .AuthToken property remains empty. As a result, the subsequent REST calls to the Vector Store service cannot authenticate correctly.
During testing, the activity returned:
.AuthToken: blank (expected a non-empty value)
Additionally, when attempting content ingestion, the log shows:
“Failed to retrieve SAX token”
We verified that the Vector Store service URL is correctly resolved through the data page “D_VectorStoreConnectionSettings” which returns:
http://genai-vector-store-service.default.svc.cluster.local:8089
This indicates that the endpoint is reachable, but the required SAX/JWT token cannot be generated. Our analysis suggests the issue is likely rooted in the runtime configuration rather than in the Pega rules, since the token generation depends on the GenAI runtime and environment settings.
- Is the previous analysis explained correct?
- Should we contact an administrator in order to check the environment settings?
- Is there any other way to fix it by ourselves?
Thankyou in advance
