Error occurs when running VisTextNet

[skim-SGFIN]

Dear Prof. Bail,

Thanks for sharing with us a great package and your detailed guidance on the R codes!

For my research, I am analyzing around 2,000 journal article abstracts, and repeatedly running into an error message "Error in if (!is.na(weights)) { : argument is of length zero" when trying to visualize it with the command "VisTextNet". (I finished protecting with the node type being "words"). Not any other option changes - e.g., alpha value or label_degree_cut - do not work, and VisTextNetD3 also does not work either.

Further, for the community detection, though it detects communities, it fails to interpret the modularity class with the command "top_words_modularity_classes" (0 observations are captured through this command).

Any relevant information would be of great help. If you need any additional information, please leave comments in this thread.
