HTTP 500 internal server error

SA-79991

Summary



HTTP 500 internal server error occurs due to pzIncludeMashupScript. Core engine does not return pzIncludeMashupScript when required during the launch of mashup. The pzIncludeMashupScript does not require authorization for access.


Error Messages

HTTP 500 internal server error


Steps to Reproduce

Log out from the mashup and relogin. The error occurs when the mashup is relaunched.


Root Cause



A button which loaded in the application was configured to log out from the Pega application. Clicking the button invoked a local Javascript function which invoked the @baseclass.LogOff activity. However, it did not clear the web sockets. Hence, an API call was triggered with the Unsubscribe push activity on opening the Pega application.

Resolution



Perform the following local-change:
Add window.msgMgrUniqueId=undefined; to the Javascript function.
