I have aJSR223 Preprocessorcode given below:

String method = sampler.getMethod();

JMeter Test Plan given below:

- JSR223 Pre Processor
      - HTTP Sampler
      - JSR223 Sampler / Any other sampler apart from HTTP

AsJSR223 PreProcessorwill apply to all the Samplers in the hierarchy, it gives below error for all the Samplers apart fromHTTP Sampler.

I want myJSR223code to run only forHTTP Sampler
