Need to replace "\x2D" on a extracted variable at Jmeter

Question

I was working with on a Jmeter script. At the 1st Response I have extract a lengthy code which I have to pass to the next request. Unfortunately, the 1st request contains "\x2D" characters , which need to be replaced with "-". Is there any way to do this. I tried with below code on a BeanShell PostProcessor, but its giving me an error.

def originalValue = vars.get("BE_stateToken");
def newValue = originalValue.replace("\x2D", "-");
vars.put("myVar", newValue);


log.info("Variable myVar value: " + vars.get("myVar"));

Below are the errors I'm getting.

We cannot help you without seeing the details of the "error" you're getting. Check jmeter.log file for any suspicious entries.

The code is almost fine, you just need to escape a backslash with another backslash:

def newValue = originalValue.replace("\\x2D", "-");

You can also consider using __strReplace() function, in this case you won't need to do any scripting. It can be installed as a part of Custom JMeter Functions bundle using JMeter Plugins Manager
