(connect ECONNREFUSED 127.0.0.1:80)

[Sam_uk]

Hi I'm trying to use N8N to create users on my Cloudron instance.

N8N is hosted on Cloudron. I get this error:

{
"status": "rejected",
"reason": {
"message": "connect ECONNREFUSED 127.0.0.1:80",
"name": "Error",
"stack": "Error: connect ECONNREFUSED 127.0.0.1:80 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1146:16)",
"code": "ECONNREFUSED"
}
}
NodeApiError: UNKNOWN ERROR - check the detailed error for more information

I see the other user(s?) with this problem are in Docker containers

@sam_uk Updating then restarting the app fixed that error for me. but can you confirm logs, app version, etc etc?

[Sam_uk]

@murgero thanks.

After a restart, I get a different error.

Form.io Trigger: Cast to ObjectId failed for value "undefined" (type string) at path "_id" for model "action"

There are some informative logs too (previously there was nothing that looked useful)

[murgero]

@sam_uk Can you install n8n to a new app and see if it receives the same errors?

[robi]

Shouldn't this be on the network that box listens on instead of localhost?

[BrutalBirdie]

@robi my thoughts as well. 127.0.0.1 should never work since this points to the docker container it self.

You should use the Domain example: my.cloudron.dev.

[Sam_uk]

@robi I'm not quite sure I understand your comment.

In N8N I have a HTTP/JSON node. Within that node, I'm trying to run

curl -X POST -H "Content-Type: application/json" -d '{ "email": "{{$node["Form.io Trigger"].json["email"]}}" }' https://my.cloudron-space.org/api/v1/users?access_token=my-token

Where {{$node["Form.io Trigger"].json["email"]}}" } is a user email from a form.io form.

[Sam_uk]

@murgero Yes same errors on a fresh install.

[BrutalBirdie]

@sam_uk can you share your exported Workflow? This makes debugging and help for us easier.

I dunno what this problem was but it seems to have gone away now
