AppetizingMouse58 In general, I first had the trains version 0.15.1, it worked. I decided to upgrade to version 0.16.0, made a data backup, but did not make the data migration, and I got the following error (the screenshot). Then I tried to make a migration, but then there was a problem, I already wrote about it. After that, I tried to roll back by downloading http://docker-compose.ml from git (with tag 0.15.1) and making docker-compose-f /opt/trainz/docker-compose.yml pull , and also restore the data folder. But now this version doesn't work for me either.
