Hey Sam,

 

 

You shouldn't need to escape characters in a character class. The hyphen needs to be the first or last character in a character class so it's not interpreted as part of a character range. Here's a related article: http://www.regular-expressions.info/posixbrackets.html

 

 

Can you try this?

 

 

STREAM::expression {@filename="[\w-]{1,200}\.[a-zA-Z0-9]{1,10}"@something@}
