Dataspace Connector UI connection ERROR

[itachiliu]

Hello， I installed the dataspace connector and the dataspace connectorUI as instructed. Here's how:

dataspace connector：
docker run -p 8080:8080 --name connector ghcr.io/international-data-spaces-association/dataspace-connector:latest

dataspace connectorUI：

sudo docker build -t dataspace-connector-ui .
sudo docker-compose up

and the docker build hint：
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it
npm WARN backend@1.0.1 No description
npm WARN backend@1.0.1 No repository field.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@2.3.2 (node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@2.3.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

but it build and execute successfully.

Next step, I access the localhost:8083, there are some error int the website:

the log show :

Then I access 'https://admin:password@localhost:8080/api/configurations' by website, it succeed.

Error: connect ECONNREFUSED 127.0.0.1:8080

So, what's wrong with my option and how to solve it，can you help me?

Thanks.

I have the same issue. I have configured a DSC and its UI using docker. I can access the connector API Swagger UI and try many of the request that the UI is giving error.

In the UI I get the same error: Error: connect ECONNREFUSED 127.0.0.1:8080

I have checked the port of the connector is correct.

I will also appreciate if anyone can provide some help to solve this issue

heya fellas, anyone managed to solve this error?

i tried changing "username" to "key" and "password" to "value" in the authentication headers, as an old issue suggested, but still no improvement.

thanks again!

I used this docker-compose.yml to solve this problem.

Change CONNECTOR_URL=https://localhost:8080 to CONNECTOR_URL=https://dc:8080

Because CONNECTOR_URL=https://localhost:8080 will access to dataspace-connector-ui self.

version: '3.5'

services:
