"Unknown Error" appears randomly after switching to Legacy Mode on Qlik Sense Server

[linushansen]

Hello!

We have built an application that runs smooth with python scripts on Qlik Sense Desktop, but when we should deploy it on Qlik Sense Server and changed from Standard Mode to Legacy Mode (first with QMC and then change Settings.ini to OverrideScriptSecurity=1 + a blank line) some strange "unknown error" appeared. (and the python scripts didnt runt but qlik didnt see any issues other than "unknown error") We have restarded the qlik sense engine services and all other qlik sense services and also tried to put it back to standard mode, but the "unknown error" still appears, and not only when loading python scripts but when loading regular apps as well. What could this issue be?

Sometimes the data gets loaded and search indexes creates successfully and then the "unknown error" pops up, sometimes the "unknown error" pops up and the data is not able to load. (exact same app) Sometimes the changes in the scripts isnt saving automatically.

When the application is ran in debug mode the "unknown error" does not appear.

Hello @linushansen 

Have you tried this:

"Unknown Error" when creating ODBC connection to Pervasive from Qlik Sense

Thanks,

By cleaning out a lot of unnecessary files and setting the Qlik server settings back to original and standard mode the problem disappeared, probably a saving issue and something locked the server on saving

I dont think it is ODBC-related unfortunately, but now I think the issues are resolved for now
