Error in get_component_(x, 1) : Not compatible with STRSXP: [type=list].

[guaribr]

I am trying to get the domain of the following link, but I get "Error in get_component_(x, 1) : Not compatible with STRSXP: [type=list]."

This is the link:
"http://www.laprensa.com.bo/nacional/20200214/policia-brasilena-desbarata-red-que-traficaba-droga-boliviana"

Thanks!
