Connection Refused between API Gateway and Ion Lambdas

Datomic Cloud
1

Hello,
We’ve been running Datomic Cloud for a couple of years and since we upgraded to 781-9041 we’ve twice run into a problem that I never encountered before.

Here’s the time line:

  • 2021-06-25 Upgrade from 668-8927 to 781-9041
  • 2021-07-19 All requests through API Gateway are failing with “Connection Refused”
    • Redeployed Ions and requests to Ion Lambdas start working again.
  • 2021-08-06 Requests are failing again with “Connection Refused”
    • Redeployed Ions and requests to Ion Lambdas start working again.

I have the API Gateway log for a test execution that I ran. It has some account specific info in it, so I won’t post the whole thing here, but here’s the section that seems important.

Fri Aug 06 13:23:42 UTC 2021 : Endpoint response body before transformations: {
"isBase64Encoded" : false,
"statusCode" : 500,
"headers" : {},
"body" : "Connection refused"
}

Has anything changed with the Lambdas that might cause this? I know 884-9095 has big changes in this area, but we’re not there yet.

Thanks,
Caleb
