Hi @MislavSag, are you able to share your Parquet file or (preferably) a
minimal sample of it that we could use to reproduce this?
When I tried to make a minimal reproduction, I find I don't get the error
you do when I set `safe = FALSE` like you do. See:
```r
library(arrow)
library(dplyr)
# w/ safe = FALSE, works fine (truncates)
arrow_table(data.frame(x=rnorm(10, 0, 10))) |>
mutate(x_trunc = cast(x, int32(), safe = FALSE)) |>
collect()
# only w/ safe = TRUE does this error (see error below)
arrow_table(data.frame(x=rnorm(10, 0, 10))) |>
mutate(x_trunc = cast(x, int32(), safe = TRUE)) |>
collect()
# Error in `compute.arrow_dplyr_query()`:
# ! Invalid: Float value -2.13185 was truncated converting to int32
# Run `rlang::last_trace()` to see where the error occurred.
```
I wonder if there's something going on where the `safe` argument isn't being
respect or if it's possible there's a typo in your code snippet?
