I have already tried with this below code but it is showing Caused by:

java.lang.NullPointerException: Cannot invoke method setValue() on null object

This is the code i have implemented but it is only accepting for the arguments passed and encrypted with jsr223 preproccessor in bodydata but not working for which wecan't apply preproccessor & this is written jsr223 post proccessor

 **String encryptedText= "${ENCRYPTEDResponseofprevREQ}";
   log.info(encryptedText);

   String decryptedText = new OpenSSLEncryptDecrypt().decrypt(encryptedText);
   log.info(decryptedText);

   ctx.getCurrentSampler().getArguments().getArgument(0).getValue(decryptedText);

   vars.put("variable",decryptedText);
   def my_var1 = vars.get("variable");
  
   log.info(my_var1);
   ctx.getCurrentSampler().getArguments().getArgument(0).setValue(my_var1);**

This line:

ctx.getCurrentSampler().getArguments().getArgument(0).getValue(decryptedText);

causes the error because ctx.getCurrentSampler().getArguments().getArgument(0) returns null and you're trying to invoke getValue() function on a null object.

Demo:

It's hard to say how to fix the issue without knowing what you're trying to achieve, but 2 things are obvious:

  1. Your HTTP Request sampler doesn't have arguments - that's why you're getting this error
  2. There is no such a function getValue(String), the function getValue() takes no parameters

Yes in http request there are no arguments I need the code to extract the value from that sampler which is encrypted to store in the next sampler Dmitri T
