Cannot get past ErrorID 520002 on Adaptive Pay API

[82rules]

I create a business account and validated my info. 

I created a REST app, and got my API credentials:

However, whether in app code or in straight curl I cannot get past this response: 

{
    "responseEnvelope": {
        "timestamp": "2017-08-26T12:17:43.633-07:00",
        "ack": "Failure",
        "correlationId": "f13da1d9917dd",
        "build": "37103655"
    },
    "error": [
        {
            "errorId": "520002",
            "domain": "PLATFORM",
            "subdomain": "Application",
            "severity": "Error",
            "category": "Application",
            "message": "Internal Error"
        }
    ]
}

An example curl input (with variable redacted) is: 

curl -X POST \
  https://svcs.sandbox.paypal.com/AdaptivePayments/Pay \
  -H 'x-paypal-application-id: APP-80W284485P519543T' \
  -H 'x-paypal-response-data-format: JSON' \
  -H 'x-paypal-security-password: ############################' \
  -H 'x-paypal-security-signature: ###########################' \
  -H 'x-paypal-security-userid: ########-facilitator@##########.com' \
  -F actionType=PAY \
  -F currencyCode=USD \
  -F cancelUrl=#### CANCEL URL ##### \
  -F returnUrl=### RETURN URL ##### \
  -F 'receiverList["receiver"][0]["amount"]=546.00' \
  -F 'receiverList["receiver"][0]["email"]=#########-facilitator@########.com' \
  -F 'receiverList["receiver"][0]["primary"]=true' \
  -F 'requestEnvelope["errorLanguage"]=en_US' \
  -F 'requestEnvelope["detailLevel"]=ReturnAll'

I can use the same credentials on non Adaptive Enpoints, not sure what I need to do to get tpast this.
