When working with the RESEARCH component, why am I seeing a message that the file format is unsupported?

This message can appear when opening a RESEARCH dashboard or when opening the Research app (Qlik > Monitoring apps > Everyone (selected from the left-menu bar) > Research app).

This indicates that the Research app is corrupted.

Possible Root Causes

Common reasons for corrupt Qlik Sense Application (QVF) files are:

  • Abnormal shutdown of the server, such as an electricity failure

  • Computer has been put into hibernate mode

  • Qlik Sense Services stopped during development

  • Not enough space on the hard drive for Windows page file

  • A high number of Qlik Sense tabs opened in the browser

  • Not enough memory

Solution

  1. Open QMC on the RESEARCH machine – https://localhost/qmc.

  2. Open the Apps section.

Since you created a new Research App, you now need to implement its new ID in the BriefCam Administrator Console as follows:

  1. In QMC, open the Apps menu.

  2. Next to the >Actions button on the top right, select the Column selector icon.
