502 Bad Gateway upon accessing the argo events webhook url

[ashishkurian]

Hi There,

I am new to Argo events and I am trying to create use case, where I trigger a workflow upon receiving an argo event from my bitbucket server.

I think I have created all the necessary resources in my EKS cluster. However, when I try to call the webhook url, I get a 502 Bad gateway error. I noticed that the k8s service that gets called from the webhook url, is of type Nodeport and I do not see any pods being added as end point to the service. This exaplains why I am getting a 502 Bad gateway error.

Is the BitbucketServer eventsource expected to create some pods in the cluster and get attached to the service?

I am attaching the manifest file I am deploying to my cluster.
