I don't see an issue at the workflow migration, because your schema is wrong: [xorm] [warn] 2023/06/28 01:24:21.639672 Table steps column step_error db type is TEXT(65535), struct type is VARCHAR(500)

https://github.com/woodpecker-ci/woodpecker/blob/e1c31df6c6e28eade007c6a6fc24bf6b9d26e203/server/model/step.go#L38

Maybe this was changed at some point, but the issue is not the workflow migration.
