   I am wondering if the following example replicates this problem.
   
   ``` r
   txt <- "a\tb\n1\t\t2"
   readr::read_tsv(I(txt), show_col_types = FALSE)
   #> Warning: One or more parsing issues, call `problems()` on your data frame for details,
   #> e.g.:
   #>   dat <- vroom(...)
   #>   problems(dat)
   #> # A tibble: 1 × 2
   #>       a     b
   #>   <dbl> <dbl>
   #> 1     1     2
   arrow::read_tsv_arrow(charToRaw(txt))
   #> Error:
   #> ! Invalid: CSV parse error: Expected 2 columns, got 3: 1     2
   
   #> Backtrace:

   ```

   Did you get an error message like the example above (``Warning: One or more parsing issues, call `problems()` on your data frame for details``) when you read that file by readr or vroom?
