Migrate fails when deploying Django to Heroku, how to solve?

Question

Django

The problems started even when executing the command git push heroku master received an error

To https://git.heroku.com/modernarchetype.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: не удалось отправить некоторые ссылки в «https://git.heroku.com/modernarchetype.git»

On the advice of SO, I created a new branch, called "tempbranch". Everything worked out.

Подсчет объектов: 6395, готово.
Delta compression using up to 4 threads.
Сжатие объектов: 100% (5328/5328), готово.
Запись объектов: 100% (6395/6395), 8.84 MiB | 57.00 KiB/s, готово.
Total 6395 (delta 1885), reused 0 (delta 0)
remote: Pushed to non-master branch, skipping build.
To https://git.heroku.com/modernarchetype.git
 * [new branch]      tempbranch -> tempbranch

Next, I run the heroku run python manage.py migrate command and I get an error:

Running python manage.py migrate on ⬢ modernarchetype... !
 ▸    Cannot run one-off process at this time. Please try again later.

Help me decide, I'm working with Heroku for the first time, and I haven't studied Django for a long time either.
