Qlik Enterprise Manager UI error: Unrecognized request parameter 'action'

[Michael_Litz]

Opening the Table Selection option in the Designer tab of a managed Qlik Replicate server, the following error may be triggered:

Error: SYS-E-HTTPFAIL, SYS-E-UNRECREQPARM, Unrecognized request parameter 'action'.. SYS,GENERAL_EXCEPTION,SYS-E-UNRECREQPARM, Unrecognized request parameter 'action'.,SYS,UNRECOGNIZED_REQUEST_PARAMETER,action

The same may be visible when clicking the Test Connection button in the Qlik Enterprise Manager. 

No additional errors are logged in the Qlik Sense Enterprise Manager log files. The issue is predominantly seen after an upgrade.

Environment

• Qlik Replicate
• Qlik Enterprise Manager

Resolution

Restart the Qlik Enterprise Manager service. 

The restart clears the browser cache, solves the issue, and prevents it from occurring again on the next load. 

Cause

After an upgrade of the Qlik Enterprise Manager (to, for example, 2024.5), UI elements in the console did not load correctly.
