Getting a 400 error on upsert text

I’m using the no-code platform Make to send an REST API request as follows, but I’m receiving a 400 error with the message “Error reading or parsing record at line 1: EOF while parsing a list at line 1 column 1”

Database config is as shown at the end.

Any ideas why?

URL: https://serene-oak-o1qqubb.svc.aped-4627-b74a.pinecone.io/records/namespaces/apps/upsert
Method: POST

Headers:
{
    "user-agent": "Make/production",
    "api-key": "***",
    "content-type": "application/x-ndjson"
}

Body:
[
    {
        "id": "c",
        "text": "d"
    }
]

Thanks for reaching out. The issue is that it expects ndjson not an array of objects. We’ll look to improve this error message.
