Exec conversions expect a tuple with an expected set of keys.
The expected keys are:
- command (string, required)
The command to run in the script.
- env (tuple, optional)
Any environment variables that should be set in the script.
The env tuple is converted using the same rules as the env converter.
- args (tuple, optional
Any command line arguments for the command line.
The arguments are converted using the same rules as the flags converter.
- Functions and Modules are ignored.
