I am getting this error when viewing my dashboard as a user but not when I'm viewing it as an admin :
The internal search "|inputlookup lookup_ossec_servers | search description!="All OSSEC Servers"" for the "Splunk.Module.SearchSelectLister" module failed.
What version of Splunk are you running? And SearchSelectLister isn't a Sideview module, but if you do have Sideview Utils installed one possible answer would be to replace SearchSelectLister with its Pulldown module in this view.
@sideview I got splunk version 6.3.1and i dont have the sideview utils app installed
If you run that search manually as a regular non-admin user, in the "search" page, does it return results or does it give an error?
|inputlookup lookup_ossec_servers | search description!="All OSSEC Servers"
Possibly the lookup has been created such that only admin users have permissions to use it and see it. The solution might be just to go to the Lookups page in the admin section (as an admin) and adjust the permissions accordingly.
