Error in connectors example

Camunda 8 Topics
1

I am trying to run the example in GitHub - camunda-community-hub/camunda-8-connector-openweather-api: A custom connector for Camunda Platform 8 to retrieve the weather forecast
but when i try to run it i am getting this error: s.c.c.OperateClientProdAutoConfiguration : An attempt to connect to Operate failed: io.camunda.operate.exception.OperateException: org.apache.hc.client5.http.HttpHostConnectException: Connect to http://localhost:8081 [localhost/127.0.0.1] failed: Connection refused

but i dont where is it configuring the [localhost/127.0.0.1] because the idea is that it points to the cloud instance.
I have already updated the env.txt with :
ZEEBE_ADDRESS=
ZEEBE_CLIENT_ID=
ZEEBE_CLIENT_SECRET=
ZEEBE_AUTHORIZATION_SERVER_URL=
ZEEBE_TOKEN_AUDIENCE=
CAMUNDA_CLUSTER_ID=
CAMUNDA_CLUSTER_REGION=
CAMUNDA_CREDENTIALS_SCOPES=
CAMUNDA_TASKLIST_BASE_URL=
CAMUNDA_OPTIMIZE_BASE_URL=
CAMUNDA_OPERATE_BASE_URL=
CAMUNDA_OAUTH_URL=
OPENWEATHER_API_KEY=

So could you plerase tell me how can i solve this? there is a similar topic How to Run Custom Connector in a Connector Runtime but as i told you i would like to get my cloud process

Hi @Juan_Felipe_Parrado - can you share how you are trying to run it?

i will use a different version of connector so i use the 0.23.2 like this:
docker run --rm --name=connectors -v “C:/Users/Admin/Desktop/xample/camunda-8-connector-openweather-api/target/openweather-api-0.1.0-SNAPSHOT.jar”:/opt/app/connector.jar --env-file env.txt camunda/connectors-bundle:0.23.2

But i have also thied the way its suggested there “docker run --rm --name=connectors -v “C:/Users/Admin/Desktop/xample/camunda-8-connector-openweather-api/target/openweather-api-0.1.0-SNAPSHOT.jar”:/opt/app/connector.jar --env-file env.txt camunda/connectors-bundle:0.2.0” and it gives me this other error:

Thanks, I wanted to confirm you were trying to run it through the Docker image. You need to use a different set of environment variables for the Connecter Runtime. Have a look at the documentation on this page and let me know if you have any questions!
