I deleted the environment variables CRON_TIME in docker-compose.yml and it works properly.

Error: Field ("0-59/1) cannot be parsed

The error shows that "0-59/1 cannot be parsed.

Do you configure CRON_TIME correctly? Maybe you forget to close quotation.

😥 It would be better if you provide docker-compose.yml file.

Have sent to giuem.com+GitHub@googlemail.com, thank you.

It's my mistake. Now it should work.

TL; DR

In docker compose file, there are two ways to configure environment variables. If using an array, docker compose will NOT strip quotes as bash did. (see docker/compose#2854)

So just remove quotes between CRON_TIME field and it works.
