🐛 Describe the bug

When I did used the fields query parameter, I noticed the API returned many other fields I did not ask for

🕵️ Expected behavior

I expected only the fields I asked for to be returned

📜 To Reproduce

curl -L --get https://pds.nasa.gov/api/search/1/products/urn:nasa:pds:msl_gt_diagenesis_supplement?fields=lid --header 'Accept: text/csv'

Confirmed this also does not work for:

• application/kvp+json
• application/json
• application/xml
