Intermittent 400 response with empty body

#1

Hi,

We have been seeing random 400 responses with empty bodies from Pipedrive lately on the API https://api.pipedrive.com/v1/persons.
It occurs intermittently with different start and limit params, while retrying the same failed request would yield successful response.

Example 400 response:

  "body": "",

    "query": "start=0&limit=500&api_token=token",
    "fragment": null
  },
  "status": 400,
  "headers": [
