Any face should either have a neighbour or a boundary condition. The face in question has non of these.

There are many sources for what you are looking for. First read OpenFOAM documentation - there is a fairly good explanation of how to use blockMesh. Additionally, from the top of my head, you could try the tutorials in the wiki page: https://wiki.openfoam.com/Meshing

Best,
Petros
