Creating an agent on a duckdb table fails interactively

[hfrick]

Following on from https://github.com/rstudio/pointblank/pull/642/files/6b0bd4a66c50c8d306d50a78a7394cc6ad740196#r2301596683.

Creating an agent on a duckdb table works when rendering the vignette, fails in interactive use - and works when sending it through reprex() so here is just the code snippet.

library(pointblank)
library(duckdb)

sales <- dplyr::tibble(
  amount = c(100, 200, 300),
  customer_name = c("Alice", "Bianca", "Charlie"),
  sale_date = as.POSIXct(c("2023-01-01", "2023-01-02", "2023-01-03"))
)

con <- dbConnect(duckdb())

dbWriteTable(con, "sales_data", sales)
sales_db <- dplyr::tbl(con, "sales_data")

agent <- create_agent(sales_db) 

dbDisconnect(con)
