After the upgrade to 4.1 all the API integrations we use stopped working:
every API response body is empty (response code is 200), whether the object requested (in case of a GET request for example) exists or not.
The same problem is found both by calling the API through PAM's API DOC portal and with powershell. Calling the API through PAM's API DOC shows the Response Body as 'no content'.
Release : 4.1
Component : PRIVILEGED ACCESS MANAGEMENT
A code change in 4.1 had a bug that caused this problem when an API key was not used for more than 24 hrs, which is why it was not noticed by QA during release testing.
Published hotfix 4.1.0.02, available for download from the PAM Solutions & Patches page. Hotfix release notes are attached here.
