It seems Snapcreator doesn't check the parameter whether it's defined/correct or not.
e.g. the wrong parameter
The snapcreator just skipps this step and ends without warning/error to say find an illegal parameter.
Could the Snapcreator verify the parameter?
Validation is done per plugins
You can add to the plugin validation files or create your own under plugins/parameters on SC Server.
If you arent using plugins then you could write a script and run it as PRE_CMD to check this and validate.
