dpasta() fails with error invalid 'times' value

[turbanisch]

I read in data from StackOverflow, hence the read_table() command. The resulting df looks innocuous but for some reason dpasta() cannot handle it:

library(tidyverse)

df <- read_table("
                 Date            burstID
2018-09-18      1
2018-09-18      2
2018-09-18      3
2018-09-18      4")

# this works: 
# datapasta::dpasta(as_tibble(mtcars))

# this doesn't
datapasta::dpasta(df)
#> Error in strrep(" ", char_length - nchar(char_vec)): invalid 'times' value
