The script '%1' contains invalid syntax for using named parameters

Error code –10236
Error constant INVALID_NAMED_PARAMETER_SCRIPT
Parameter 1 Name of script.
Probable cause

The script does not contain a properly formed named parameter sequence. To reference a script parameter by name, enclose the parameter in curly braces and prefix it with ml, as in {ml parameter}. For example, {ml s.action_code}.
