amazon web services - Elastic Beanstalk: dictionary update sequence element #0 has length 1; 2 is required -


we had working elastic beanstalk environment, after adding config file, we've started getting error during deploy:

error occurred during build: dictionary update sequence element #0 has length 1; 2 required

the config file looks this:

# .ebextentions/seed.config container_commands:   01_set_tenant_gateway:     command: rake db:seed:set_tenant_gateway     leader_only: true     env: our-env

the log gives this:

2015-04-09 18:27:48,220 [debug] running command seed_tenant_gateway 2015-04-09 18:27:48,220 [debug] generating defaults command seed_tenant_gateway <<<

what might going on here?

1) syntax env key:

env:      <variable name>: <variable value>

2) also, need enclose command in quotes:

command: "<command run>"
