[igraph] converting graph objects to data.frame

Dear all, 

I am trying to convert an igraph object into a data.frame. As I am interested in the vertex attributes (I need to extract some network characteristics to be included into an econometric analysis), I do 

net.df <- as_data_frame(net, what = 'vertices')
However, this does not work. It did work the first time I used the command, but for some reasons now it returns the following error:

Error in as.data.frame.default(value, stringsAsFactors = FALSE, ...) : 
  cannot coerce class ""igraph"" to a data.frame

I had to replicate some analysis, but the only change I made concerned a few more attributes that I computed to be extracted. Any suggestion?
