I'm using the Update endpoint, with the request straight from the documentation:

curl 'https://[nation].nationbuilder.com/api/v1/people/[id]?access_token=[token]' -X PUT -H 'Content-Type: application/json' -d '{"person":{"first_name":"Joe","email":"[email protected]","phone":"303-555-0841"}}'

I receive this response:

{"code":"server_error","message":"You have encountered a server error."}

This is after creating a record using the People Create endpoint, and verifying the record is available with the People Show endpoint.

Any help appreciated.
