CAHVS0251E Invalid Credentials With API after LU10439 OM Web Viewer 14.0

Products

• Output Management Web Viewer

Issue/Introduction

We upgraded Web Viewer to LU10439  Modern User interface Build: 14.0.65 ( REACT ). The GUI is working fine but we can't access the API anymore on the new version. We still have the old version running on production and the exact same API call does work there. 

The new version gives: 

{"result":{"name":"%","order":"id","limit":10000,"offset":0,"groupRepositoryType":"selectavail","repositoryCount":0,"sessionId":111},"message":[{"shortText":"Invalid Credentials","longText":"CAHVS0251E Invalid Credentials","locale":"en-US"}],"status":"ERROR"}

Environment

• Output Management Web Viewer 14.0
• Output Management Web Viewer™ for z/OS

Cause

Username and password authentication via API endpoints other than the login endpoint has been removed at this level. Starting with this LU10439  Modern User interface Build: 14.0.65, all operations (other than the login operation) require a session token to authenticate.

Resolution

Starting with build 14.0.64 (LU10439 Modernized User Interface), support for using username/password was removed for all endpoints except login.

1. The login endpoint needs to be used to generate a session token (guid)
2. Then the guid is used for all other endpoints.

This is documented in the Release Notes Obsolete Features section "Removed Features" (Non-login username and password authentication removed (PTF LU10439)).
