Getting back to the topic, I was able to solve the problem and I want to share how I did it. At first I was puzzled that the error was that the folder didn't exist, but it did. If I opened a shell in the rclone container I could see that folder. So, searching a lot I found that rclone, for some reason I don't know, wants to mount them in the /data folder, and I wanted to mount them in /mnt.
