Qlikview Documents that use Server Side Extensions (SSE) / Advanced Analytics Integration (AAI) in the Load Script Fail When Reloaded With Generic Errors
Article Number: 000052826 | Last Modified: 2018/06/27Description
A Qlikview document has been created that calls a Server Side Extension (SSE) / Advanced Analytics Integration (AAI) function in the load script. This works locally in Qlikview desktop, but when this file is reloaded on Qlikview Server it fails with generic errors such as:

(for context, calling an SSE function Script such as Script.ScriptEval('arg[0]...)
- Qlikview Server, Nov2017
Cause
The QVB does not get its settings from the QVS.
Therefore, in order for the QVB to call the SSE function in a load script while reloading a document, it must have a copy of the same SSE settings as the QVS.

Resolution
This is a documentation bug in the SSE Github repository.
Add the SSE settings to the QVB settings file, in addition to the QVS settings files. In summary, the SSEPlugin=<EngineName>,localhost:<port> setting should be in two locations:
