sum(..., na.rm = TRUE) creates a fall_back

[meersel]

Using the base sum() function with argument na.rm = TRUE creates an fall_back to dplyr.
The argument na.rm is not recognized.

Example code:

duckplyr::as_duckplyr_tibble(my_tbl) |>

summarise(
total_sales = sum(sales_col, na.rm = TRUE),

.by = c(country, item_number)

)
