CSV Data Config Not Sending Data to HTTP Request

Question

I have recorded a test script for user authentication and am trying to send data by using a CSV file. I have tried this previously for a post request and the parameters were being sent fine but it doesnt seem to be working for the test script.

The error i get in my response body from the result tree is: {"EXCEPTION":"com.google.gson.JsonSyntaxException","ERROR":"com.google.gson.stream.MalformedJsonException: Unterminated object at line 1 column 16 path $.username"}

Attaching screenshots below for you to understand better.

Variables I've set for authenticate call

Answer 1

We cannot help without seeing:

1. First 2 lines of your CSV file
2. Whether the variables are getting read by JMeter (output of the Debug Sampler )
3. What request is actually being sent to the server (Request -> Request Body) tab of the View Results Tree listener
4. Any suspicious entries from jmeter.log file
