When "one or more objects failed to apply", where to look for details?

[larsks]

I'm using ArgoCD via Red Hat's GitOps operator (so that's v2.0.0). I've created a simple ApplicationSet that generates a single Application, which in turns is supposed to set up a small number of resources (namespace, deployment, configmap, service, route).

The ApplicationSet is able to create the Application without a problem, and the Application is then able to create the Namespace and the ConfigMap, but the remaining resources never get created. ArgoCD itself tells me only that "one or more objects failed to apply".

The resources apply just fine if I create them manually via oc apply.

Looking at the logs from the application controller pod, I don't see any obvious errors related to these resources. Mostly just this:

time="2021-05-05T13:39:53Z" level=info msg="sync/terminate complete" application=oai-demo-webserver duration=7.908478826s syncId=00012-wrCNk
time="2021-05-05T13:39:53Z" level=info msg="updated 'oai-demo-webserver' operation (phase: Failed)"
time="2021-05-05T13:39:53Z" level=info msg="Sync operation to e11642171eec2d1cf57b2acc5fedc82496e80efa failed: one or more objects failed to apply" application=oai-demo-webserver dest-namespace=openshift-gitops dest-server="https://kubernetes.default.svc" reason=OperationCompleted type=Warning

Where do I look for details?

The answer is that the specific errors are visible when you click on the "Sync Error" message in the application detail screen.
