Error msg while stacking data frames into one data frame

[KMikhail]

While trying to stack dataframes I received an error message.
This is my code:
all_trips <- bind_rows(q1_2019, q1_2020)

And this is the error:
Error in bind_rows():
! Can't combine ..1$ride_length and ..2$ride_length

I compared both tables and I want to change the datatype in q1_2020 for the column ride_length into but don't know how.

We need some more information: what are the datatypes for ride_length in q1_2019 and q1_2020, and what do you want it to be?
