To save array data, you need stringify first which is mentioned here https://learning.postman.com/docs/sending-requests/variables/#understanding-variables
const res = pm.response.json();
const rolepermission = res.data[0].rolepermission;
pm.environment.set("rolepermission", JSON.stringify(rolepermission));
Use this variable in request body:
{
"role": {
"name": "{{rolename}}",
"description": "{{roledescription}}",
"permissions": {{rolepermission}},
"userType": "{{roletype}}"
}
}
