I tested with the request.http example and it returned internal server error

POST {{baseUrl}}/v1/extract HTTP/1.1
Authorization: Bearer {{$dotenv TEST_API_KEY}}
Content-Type: application/json

{
  "cacheMode":"load",
  "cacheKey":"testt",
  "urls": [
  ...

{
 "success": false,
 "error": "Internal server error"
}
