Steps to reproduce:
In a space Integrate VPRT and SCM in Advanced plugin settings (or using Add-ons menu in VPRT 2.2)
Either create an initial language or an initial version (enabling either Versions or Translations in Viewport settings is not required!)
Open a theme in Viewport
Type one of the characters above, and hit Enter
Viewport should handle the error response better by giving user "Nothing found" placeholder.
Viewport throws an error and transfers user to Confluence interface.
