Warning message: data_frame() was deprecated in tibble 1.1.0.

I am getting the following error message in R

Error in as.data.table(tm[c("link", "datetime")]) :
could not find function "as.data.table"
In addition: Warning message:
data_frame() was deprecated in tibble 1.1.0.
ℹ Please use tibble() instead.
ℹ The deprecated feature was likely used in the wayback package.
Please report the issue at https://github.com/hrbrmstr/wayback/issues.
