I have extracted the jwt token from the **User login controller** through my http service my test plan looks like this: [![Result tree][1]][1] [![Test plan][2]][2] As seen in the images in login request it takes the header of **Breakdown Configuration** and it doesn't take authorization token value pass as a JSON object in `Bearer ${token`} although I have extracted it in JSON extractor and debug sampler shows it. I have also used the once only controller but it doesn't solve the issue. Please help in the nested Header Manager and how to use it correctly. Even I have used **Bean Shell processor** under my GETALL Bd-config request and pass the command: ``` import org.apache.jmeter.protocol.http.control.Header; sampler.getHeaderManager().add(new Header("Authorization","Bearer " + vars.get("BEARER"))); ``` But it doesn't solve the issue. Please guide. [1]: https://i.sstatic.net/JREvT.png [2]: https://i.sstatic.net/GFzgE.png
