Description: "Perform script by name" script step fails when calling a script with a name that includes colons (punctuation mark).
Example: Perform script by name ["This: is a script"]
How to replicate: I have attached a sample file where two different scripts are called using "perform script by name". When the one that has a colon punctuation mark in the name is called, it shows an error " Script is missing".
