It looks like these are the actual errors:
/tmp/guix-build-deja-dup-34.3.drv-0/deja-dup-34.3/libdeja/ToolPlugin.vala:78.7-78.40:
 error: Assignment: Cannot convert from `GLib.List<weak GLib.File>' to

      this._restore_files = value.copy();

It probably keeps going after the errors due to make's parallelism.
