Tidyquant: tq_get - Warning message

Hi

I am quite new to R so not sure if this is something that is common knowledge but after some excessive googling I have not found a similar error

I'm looking for some assistance on a warning I am getting. I get the result that I am expecting in the form of a dataframe but when I try to insert the data into a ggplot in a shiny app the warning pops up instead of the graph. I've narrowed the warning down to the getting of stock prices from tq_get and removed everything bar what is causing the error. I've included a repex below also

The warning I am getting is:

#> Warning: type_convert() only converts columns of type 'character'.
#> - df has no columns of type 'character'

Any help is greatly appreciated!

library(tidyquant)

prices <- tq_get("TSLA",
                 get = "stock.prices",
                 from = "1990-01-01")
