Function call inside another function is not getting evaluated [JMeter]

I am using function call inside another function in JSR223 Pre Processor

  1. Getting the Request Body from Parent HTTP Sampler

    String requestBody = sampler.getArguments().getArgument(0).getValue();
log.info("Request body is : " + requestBody);

  2. Value getting processed properly in __V function

    log.info(${__V(requestBody)});

  3. Same __V function is not getting evaluated inside MD5 function

    String md5hash = "${__MD5(${__V(requestBody)},)}";
log.info("md5hash is : " + md5hash);

  4. JMeter log is given below:

    2022-03-17 15:10:01,135 INFO o.a.j.m.J.JSR223 PreProcessor: Request body is : {
    "contact":"1234567890"
}
2022-03-17 15:10:01,135 INFO o.a.j.m.J.JSR223 PreProcessor: {
    "contact":"1234567890"
}
2022-03-17 15:10:01,135 INFO o.a.j.m.J.JSR223 PreProcessor: md5hash is : 
1be38aa366c4b7daef5e4b527902a97b

The MD5 hash generated at step 4 i.e. 1be38aa366c4b7daef5e4b527902a97b is of requestBody text. I want MD5 to be generated for requestBody variable.

Don't inline JMeter Functions or Variables in Groovy scripts, as per JSR223 Sampler Documentation:

The JSR223 test elements have a feature (compilation) that can significantly increase performance.

When using this feature, ensure your script code does not use JMeter variables or JMeter function calls directly in script code as caching would only cache first replacement. Instead use script parameters.

In order to generate MD5 checksum of the requestBody variable use the following code:

def md5hash = vars.get('requestBody').md5()
