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}}"
  }
}
