Connection refused when I try to register a new user with @fusionauth/typescript-client

Hi dear reader

I am using Docker and terraform to configure my dev env in my PC and everything looks good, and by good I mean I can go to http:localhost:9011 and login as a super admin. My terrafrom also seems fine. But the issue is when I try to execute my integration test to verify that I can register a user. It fails with this error:

{
  message: 'request to http://localhost:9011/api/user/registration/ failed, reason: connect ECONNREFUSED 127.0.0.1:9011',
  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED'
}

I am pretty sure that the configuration is working and I am passing the api key, tenant id, and host. So I am at a total lost and I hope you can help me to understand what is wrong. Meanwhile I'll try to fix it and if I managed to do it you can see it in my repo.

Where I configured fusionauth SDK

Where I am using SDK to register a new user

Integration test suit

Note: I checked the env variables and logged them in the console and everything seems to be fine as far as I could make sure.

How to run the tests:

Clone the repo
cp .env.example .env
npm ci
npm i -G nx
nx start:docker backend-e2e

I guess I found out the issue, it was related to docker and networking, it seems that when I run the nodejs app on its own on my local env and just dockerize fusionauth and its stack it is working but now when I dockerize my nodejs app alongside the fusionauth. Any idea on what is wrong?

I created a smaller and simpler version to reproduce this situation, you can find it here: https://github.com/kasir-barati/docker/tree/docker-compose/docker-compose-files/fusionauth-nodejs

When I used @fusionauth/node-client SDK it thrown this error:

{
  "statusCode": 500,
  "errorResponse": null,
  "successResponse": null,
  "exception": {
    "errno": -111,
    "code": "ECONNREFUSED",
    "syscall": "connect",
    "address": "127.0.0.1",
    "port": 9011
  }
}

I am pretty sure I am missing something here but dunno what is it

Any help?

Now that I've followed the troubleshooting guideline I have realized that when I send a req directly to the fusionauth api via Curl it is working and it can create the user. So all is left is to dig in a little more and figure out what is wrong with the client libraries or to be more precise what I am doing wrong

Curl

curl -X POST \
  http://localhost:9011/api/user/registration/ \
  -H 'X-FusionAuth-TenantId: 40b82d21-2343-40e3-bae0-20b63210bd96' \

  }
}'

I had to access fusionauth instance with its service name and not localhost . Just look at my .env.example to understand what was wrong.

@kasir-barati Thank you for sharing with the community!

Hey folks,

Coming from the future. I just decided to change my docker-compose.yml to use network_mode: host therefore my former comment is no longer valid. Please look at my monorepo on how I am utilizing Terraform, Docker, mailcatcher as my local SMTP, NestJS, and NextJS.

I also wrote a couple of README.mds here and there for future references.

Feel free to give it a star on GitHub and or better yet use it.
