[DSpace Community]

Hi,

This error sounds like a communication problem between the frontend & backend.  It's likely caused by one of the issues described in this common installation issue ("No _links section.")

https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface

Keep in mind, we also don't recommend running the User Interface directly via Node in the way you are trying to achieve.  Instead, please see our User Interface installation guide for how we recommend running the user interface: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-FrontendInstallation
