ActiveRecord::Schema.define(version: 2021_12_17_090228) do
create_table "tasks", charset: "utf8mb4", force: :cascade do |t|
- t.datetime "deleted_at"
+ t.datetime "deleted_at", precision: 6
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
endI think there was a lack of compatibility considerations in #42297.
