problems in later R versions.

[glilienthal]

I hope this fixes the error I received when running the following in R 4.4.0.

dw_list_charts()

Error in default.stringsAsFactors() : 'default.stringsAsFactors' is defunct. Use 'stringsAsFactors = FALSE' instead. See help("Defunct")

However, running this I get

dw_list_charts()

Error in (function (..., deparse.level = 1, make.row.names = TRUE, stringsAsFactors = FALSE, : invalid list argument: all variables should have the same length

I still send the pull request, as it might help.
