col_time(format = "") error

In the original CSV file, there is a column "ride_lenght" , which is "TIME".
When importing CSV file using read_csv(), it is shown type of column "ride_lenght" as col_character(). Its type should be "col_time(format = "")"
Please advice.

── Column specification ─────────────────────────────────────────
cols(
ride_id = col_character(),
rideable_type = col_character(),
member_casual = col_character(),
ride_lenght = col_character(),
day_of_week = col_double()
)

Just specify the col_type:
