Hi @sravanesr, thank you for using the plugin, you lacked a quote in the metaData INCORRECT: {"Authorization": Bearer Token"} CORRECT: {"Authorization": "Bearer Token"} In getting started, I'd attached the jmx file, you can see which doesn't lack that quote. Best regard Thoai Nguyen

Hi @sravanesr, sorry for the late response The plugin requires two things to run :

[x] A .jmx file (the above .jmx file is OK)
[ ] A .jar is packaged from *.proto file, you can achieve it by follow 1) go to folder docs/example/grpc-lib in repository 2) put the hello.proto into src/main/proto 3) execute command mvn clean install 4) move grpc-lib-0.0.1.jar to {jmeter_home}/lib/ext

Hi @sravanesr, You must execute command mvn clean install in the directory docs/examle/grpc-lib Best regard Thoai nguyen
