Internal Client Exception intermittently

I have a query that runs every minute in the background using async calls. It’s been working fine during development for a week or so, but I’ve started getting

code: ‘Internal client exception’, message: ‘https://api.backendless.com/v1/binary

every so often today. Is there something wrong with the servers?

Is it possible you’re going over the 50 API calls/minute limit?

Shouldn’t be the case, it’s set to do the query once every MINUTE, even with app launch setup like fetching the user and whatnot I can’t see it going over 10 calls in the first minute of the app.

Could you describe what each request does?
