The body is non-manifold.  It contains a face or edge that does not have a manifold connection to the body (which means it may not be manufacturable) or it has bad topology (which is an error condition which prevents the paver from working).  Non-manifold connections mean that multiple solids should be created from the surfaces selected. To isolate and fix bad topology (if surfaces cannot be used to create multiple solids), try paving neighboring general trimmed surfaces to find the surface that won't pave, disassemble it, reassemble, and try pave meshing again.  Once the paver can pave the surface, then try creating the B-Rep solid again.
