We just upgraded our Production environment from UIM version 20.1 to 20.3. After the upgrade, we ran into the same issue we had after previous upgrades when the Webservices REST API stopped working.

Error when opening version-info page using web browser:

HTTP Status 500 – Internal Server Error
Type Exception Report
Message Servlet execution threw an exception
Description The server encountered an unexpected condition that prevented it from fulfilling the request.

javax.servlet.ServletException: Servlet execution threw an exception
Root Cause

Note The full stack trace of the root cause is available in the server logs.


Release: 20.3

- UIM upgraded from 20.1 to 20.3

- webservices_rest v20.30


1. Download new Test fix package-> webservices_rest v20.30T1

2. Deploy the package to the Operator Console robot

3. Run a simple webservices_rest call, e.g., /<host>/rest/version-info

The HTTP Status 500 – Internal Server Error should no longer occur.
