The Aviary web service requires command arguments for all jobs submitted in cumin via Aviary. Cumin does not supply a command arguments value to Aviary if the user does not specify arguments. This is a problem for commands that take no arguments.
Submissions that specify commands without arguments will be rejected with an error. This applies to regular submissions and VM submissions.
Cumin supplies a null command arguments value to Aviary when no command arguments are specified by the user.
It is possible to successfully submit commands with no arguments as jobs from cumin.
