@lionel- From tidyverse/dplyr#4614

A similar issue is happening when using bind_rows() with a column of periods on dplyr_0.8.99.9000:

  test <- list()
test$a <- data.frame(a = rep(lubridate::now(), 10), p = rep(lubridate::hm("0:30"), 10))
test$b <- data.frame(a = rep(lubridate::now(), 10), p = rep(lubridate::hm("0:50"), 10))

dplyr::bind_rows(test)
#> Error: No common type for `a$p` <Period> and `b$p` <Period>.

Looks like this would be taken care of with tidyverse/lubridate#721
