Airtable GET request (single record response with Record ID in query string or first 20 without)

This working sample will return a single record in the response when a query string value is present (from the key "recid") or will return the first 20 records when no query string value is present.

Notes:

• Performs no validation on the record ID; invalid values will meet the catch condition
• A sort configuration (by field "Year") is present, which may simply be omitted or revised to your need
