params null error

Question

Hello, I am using the "Employee Search (Sales Nav)" scraping process. I have a problem. When the parameters that require id or code are null or "", the request throws an error. 
 If I write "0" instead of the empty id, will it cause an error in scraping?
How can I solve this? Thanks.
error: "message": 
"400 - "{"data":null,"message":"Bad request: Invalid geo_codes. One or more of the geo_codes is not valid. You will not be charged for this request."}

Hi Ahmet,
I've reviewed your log and noticed that you wish to filter all profiles in the most detailed manner. However, please note:

1. You do not need to insert a parameter if you do not intend to use it.
2. Kindly refer to [our tutorial](https://rapidapi.com/freshdata-freshdata-default/api/fresh-linkedin-profile-data/tutorials/search-employees-endpoint-payload-references) to understand which values can be passed into each key.

Please let me know if you continue to encounter this error or any others.
