'Assigning regex to a string variable is giving error when using in Jmeter Post processor using Groovy

I am trying to assign regex to a string so i can use it later for partial string extraction. Somehow it doesn't like it when grouping is used

I need to use regex = (,"action")(.*?)(})

def res =prev.getResponseDataAsString(); strRegExp = ~"(,"action")(.*?)(})"

// def strRegExp = ~',"action"' // This is working fine

def strRel = res.minus(strRegExp)

Giving below exception :

javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: Script34.groovy: 66: Unexpected input: '"' @ line 66, column 28. def strRegExp = ~"(,"action")(.*?)(})" ^

Solution 1:[1]

You need to use something like:

def strRegExp = "(,\"action\")(.*?)(})"

or use single quotes instead of double quotes:

def strRegExp = '(,"action")(.*?)(})'
