When running the installable cloud application, the following error occurs: Session fails to respond (Invalid session).
Cause:
This error typically occurs during script replay for application load testing when the Enable HMAC-based client message authentication option is enabled.
Because HMAC enforces strict request integrity validation, and replayed requests typically contain missing or invalid signatures, causing the server to reject them as invalid sessions.
Solution:
Do not select the Enable HMAC-based client message authentication option in the project painter > Security page if you want to perform load-testing for the application.
