Do you have an access to the original application on the system it's coming from? If so, try to open the file without the data, save it and export it.
Another thing to check: verify if you have enough space on the target Hard Drive on your system. You should have enough space for ~2x of your imported file (to handle Temp storage), at least....
Facing same problem while importing certain app.
I am trying to import certain app at qlik sense by QMC but faced certain error:
Invalid path :Invalid path (Path longer than 260 characters) (HTTP code: 500) 37543937-a22e-4ae6-82b5-65147fdb8b69
This is to mention that I can import other apps from the same location then why received such error (Path longer than 260 characters) as well as same app can be accessed by Qlik sense desktop.
Try to change the app's name to something simple (like "123.qvf") and without periods and spaces in the file name before the import...
Qlik is well known for incorrect messages in logs, so this "Path longer than 260 characters" might be misleading..
And which QS server version are you using? I can try to replicate the issue on my system...
Yep I renamed with only 3 Character like "CEM.qvf" instead of "02.CEM Communications.qvf". I think you r right error message seems misleading.
Qlik Sense server 11.14.3 release September 2017
