I've been working on a new PayPal integration via the REST API. Everything was working in my integration tests last week and I had to take a few days off to work on some other projects and priorities. Yesterday my tests all started responding with "INTERNAL_SERVICE_ERROR" response codes (500 errors).
`{ "name": "INTERNAL_SERVICE_ERROR", "message": "An internal service error has occurred", "debug_id": "8c87a26cb48e9" }`
That was a request to `v1/identity/oauth2/userinfo` but other requests I've tried respond the same.
Authorization requests seem to work fine.
Requests with production (non sandbox keys) work fine.
I got on Gitter yesterday (https://gitter.im/paypal/paypal-checkout?at=5c5365e5454aad4df7d41016) and was told there *may* be an issue with the REST API sandbox but I can't quite tell what's actually happening here.
The API status doesn't report any issues: https://www.paypal-status.com/api/sandbox
Am I losing my mind or is there a sandbox issue?
