Hello everyone, currently I am developing a new load testing framework with k6 and webpack bundle to build it up and I am facing a couple of errors, I don’t know what I am doing wrong hope you can help me!

As you can see in the image code is very simple

 ![Captura de Pantalla 2022-08-25 a las 18.16.25](https://us1.discourse-cdn.com/grafana/original/2X/b/bbf6d2f9d88c73500e90e93ca031383f75057987.png)

Have 2 groups \>\> One that uses a ‘Common’ class to call and endpoint, only one time, to get the authorization Token, and the other group that contains the testing http.get methods

**1. Use of session**  
As you can see I am using session to do all the http calls. This session variable is created in ‘Common’ class to setBaseUrl properly one time. The issue is that when I use default http.get or http.post I get this error, that forces me to use session.  
**TypeError cannot read property post of undefined or null**

**2. 401 Unauthorized**  
So first endpoint works perfect, I get the auth Token right but when I do the first get request I get 401 unauthorized, which makes no sense because I put same request on thunder client/postman and I get all the info with 200 OK.  
As i cannot get more info I decided to debug \>\>

 here we can see a couple of things: the groups doesn't coincide exactly with my code, and the request that is doing contains "Content-Type": application/x-www-form-urlencoded when I am explicitly sending 'application/json'

To finish I share also the common class, where if I change this session.post() with http.post (Importing http from 'k6/http') I get same TypeError cannot read property post of undefined or null

Thanks everyone! Hope everything is clear.

Hi @NilPascual !

> **1. Use of session**

That’s interesting. Could you please adjust the original post since the formatting hides the image?

> **TypeError cannot read property post of undefined or null**

Could you please provide a script file that errors with such a message?

> **2. 401 Unauthorized**

In the first GET request, I see neither `Content-type` nor `access-token.` This probably means that something meaningful can be in the `common.getUserSession`, so, please attach it there 😌

Cheers!

Hello, thanks for the answer, the issue was that when you use that session() thing with httpx, get() method changes to get(url, body, params) which makes no sense 'cause, if I am not wrong, get methods don’t send any body, but I do now the same call this way session.get(url, null, params) and works.
