Hello lyssieth and welcome to our forum!
First note, you shouldn't use the All-in-one or mono-container deploy method, its deprecated.
Besides this, it seems like you found a bug, I'll try to fix this as soon as possible. I guess for some reason its not supported anymore to have the options BEFORE the command, which is the reason for celery to fail to run. I will include a fix with 1.2.1.
