Hey everyone! I am using Nhost serverless functions to connect to the Hasura Events. I have an event set up for a specific function but when I trigger the function from the hasura console (or by an INSERT, UPDATE, or DELETE operation) I get this as the response…

  "data": {
    "message": "{\"type\":\"http_exception\",\"message\":\"Connection failure\",\"request\":{\"secure\":false,\"path\":\"/v1/functions/workspace-event-insert-workspace-log\",\"responseTimeout\":\"ResponseTimeoutMicro 60000000\",\"queryString\":\"\",\"method\":\"POST\",\"requestHeaders\":{\"Content-Type\":\"application/json\",\"X-B3-ParentSpanId\":\"aa2c937007b3b668\",\"X-B3-TraceId\":\"b9b1698b8f23b8e2\",\"X-B3-SpanId\":\"6b2baa2b62719f2e\",\"User-Agent\":\"hasura-graphql-engine/v2.8.1\",\"nhost-webhook-secret\":\"nhost-webhook-secret\"},\"host\":\"localhost\",\"port\":1337}}"
  },
  "version": "2",
  "type": "client_error"
}

As you can see I am doing this with the CLI on my local machine. I would say that I have the url wrong or the serverless function wrong but when I enter the url into a browser I get the response "OK" so I know it is hitting the serverless function and it returns OK. Any ideas why Hasura can't seem to connect to my serverless function?

Hmm, looks good. What OS are you on? I suspect this is a local issue due to the fact that the current CLI runs Hasura in a Docker container and serverless functions on the host machine. It will be different in our updated CLI where everything will be running inside docker containers in the same docker network.

I am runnung Ubuntu 20.04

Just as a bit of information. I was able to get the request to hit the serverless function if I used the IP address of my machine rather than localhost. This would probably be a helpful thing to have in the nhost docs until the updated CLI has everything inside of docker containers.

Yea this is 99% an issue with Ubuntu and the fact that I mentioned above. Will be fixed with this PR:: https://github.com/nhost/cli/pull/257

eta 1-2 weeks max. Hopefully much sooner.
