hoverinfo not working - unable to reproduce franconia plotly map with correct hover information

I am building a map using plot_ly and am unable to correctly display information using text and hoverinfo. To debug, I tried to recreate this map found on this website:
https://blog.cpsievert.me/2018/03/30/visualizing-geo-spatial-data-with-sf-and-plotly/

plot_ly(
  franconia,
  split = ~NUTS_ID,
  color = ~district,
  stroke = I("black"),
  text = ~paste(NAME_ASCI, "\n is in", district), 
  hoverinfo = "text",
  hoveron = "fill"
)

however only the nuts_id information is showing.

Thus, when I run this code:

 plot_ly(data = full_pov_census_data, 
            split =~NAME, 
            color =~NumbImpoverished,
            showlegend = FALSE,
            alpha = 1,
            type = 'scatter',
            mode = 'lines') 

only the NAME variable shows up when I hover.

Do you mind helping me solve this problem?

Thank you in advance

Commencez par les deux exemples plot_ly fournis et comparez leurs paramètres split, text, hoverinfo, hoveron et mode avec l’exemple Franconia lié. Reproduisez le comportement à l’aide des entrées franconia et full_pov_census_data ; l’issue est terminée lorsque le texte attendu et les informations sur le district ou la pauvreté apparaissent au survol, plutôt que seulement name ou NUTS_ID.
