Hi,  
have a doubt with setting up random values to environment level and use it.  
Actually I wanted to add a random word in place of name and namekey and set it in environment level. So I have attached the code. But it’s going as undefined error always. I am not if I can do this with the below code. So my body is always dynamic so I want to generate random words/word, whenever it runs and set it and use it for other request. So that always I can have new values without input.Thanks in advance,

**POST body :**

[  
{  
“name”: “{{categoryName}}”,  
“nameKey”:“{{categorynameKey}}”  
}  
]

Code : **Pre-request Script**

var random1=“{{$randomLoremWords}}”;

var random2=“{{$randomLoremWord}}”;

var categoryName=pm.environment.get(“name”) + random1

console.log(categoryName);

var categorynameKey=pm.environment.get(“nameKey”) + random2

console.log(categorynameKey);

pm.environment.set(“caetegoryName”, data[0].categoryName);

pm.environment.set(“categorynameKey”,data[0].categorynameKey);
