Jmeter : Read data (numbers) from CSV file in Jmeter - csv

Question

I'm trying to design a load test for some APIs, I need to read the data from a CSV file, Here is my CSV file :
amount,description
100,"100 Added"
-150,"-150 removed"
20, "20 added"
the amount is a number.
My CSV data config looks like this:

When I put the body data like this :

I have this error :
{"timestamp":1529427563867,"status":400,"error":"Bad Request","message":"JSON parse error: Unrecognized token 'amount': was expecting ('true', 'false' or 'null'); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'amount': was expecting ('true', 'false' or 'null')\n
and when I change it to this:
Image
I have this error:
"timestamp":1529427739395,"status":400,"error":"Bad Request","message":"JSON parse error: Cannot deserialize value of type `java.math.BigDecimal` from String \"amount\": not a valid representation; nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.math.BigDecimal` from String \"amount\": not a valid representation\n at [Source: (PushbackInputStream); line: 2, column: 13]
How should I pass the parameters to be able to read from the CSV file?
P.S it works fine when I do all the things without CSV.

Answer 1

In your config, you have "Ignore first line" set to False.
Options:
1: Set "Ignore First Line" to True, for source files with header data included.
2: Leave the config setting as is, but remove the headers from the CSV source file.
