Progress 7/28/20: I can almost replicate the error in creating nwdf (server.R#534) with the nursing home data, but not quite.

Using the following code to read in the network data (pulled from _server.R#141),

try({nursing <- network(read.csv('NursingHomeMatrix.csv', sep=",", header=FALSE,
                                row.names=NULL),
#                  directed=input$dir, loops=input$loops,
#                  multiple=input$multiple, bipartite=input$bipartite,
#                  matrix.type=input$matrixtype,
                  ignore.eval=FALSE, names.eval='edgevalue')
     })

stepping through subsequent code gives me the following for nwdf instead of throwing an error:

The way I've read in the data assigns one attribute called "vertex.names", instead of no attributes.

JEANETTE START HERE Investigate the options of the network() command. The defaults the Shiny app sets must be different than the defaults of the network() command or different from header=TRUE or row.names=NULL for read.csv().

[netterie]

No that can't be it - when you upload the network, the app does show "vertex.names" as an attribute.

I'll turn off extraneous elements of the UI and add some extra textOutput to see what if I'm replicating nwdf incorrectly.
