Fileinfo: Incorrect Content-Length

Content-Length header is incorrect.

Example:

curl -X POST --header "Content-type:application/json" https://v4.provider.polygon.oceanprotocol.com/api/services/fileinfo -d '{"type": "url","url": "https://vaccovid-coronavirus-vaccine-and-treatment-tracker.p.rapidapi.com/api/npm-covid-data/", "method": "get", "headers":{"X-RapidAPI-Host": "vaccovid-coronavirus-vaccine-and-treatment-tracker.p.rapidapi.com","X-RapidAPI-Key": "REDACTED"}}'

outputs:

[{"contentLength":"","contentType":"application/json","index":0,"type":"url","valid":true}]

When calling the url:

curl -I -X HEAD --header "X-RapidAPI-Host:vaccovid-coronavirus-vaccine-and-treatment-tracker.p.rapidapi.com" --header "X-RapidAPI-Key: 1f811eb1f4msh4c465d8347c3bccp1ef1cfjsn011962fe9903" https://vaccovid-coronavirus-vaccine-and-treatment-tracker.p.rapidapi.com/api/npm-covid-data/
