Deploying from test server to production Server in qlik sense

[Pomna]

Hello experts,

I need help deploying a qlik sense app from test server to production server. I tried exporting the app and importing the app to production server but got the following error "Cannot read property 'map' of undefined". I would appreciate any suggestions  how to go about this. Thanks

Few things you may need to check

• Check both test & prod server are in same version?
• try exporting & importing in to the same test server, is this worked?
• Any extensions used in the app, which is not available in prod server?
• Are you trying to open the app in same browser, check the browser compatibility.

Thanks for your response. I exported from the test server, imported to the production server using export and import in the QMC. Then, I linked the data source to the production server.
