Deployment of ArgoEvents example sensor fails, but kubectl command does it without an issue

[comtihon]

I package my workflows (sensor + event source) in helm package during ci/cd. In the argocd manifest I specified this package to be installed. I found it convenient as we have multiple workflows repo and a single infra repo where we mention it together with other apps. But the problem I faced is - when it tries to install it via ArgoCD - it installs event source without any problem, but it fails to install the sensor: admission webhook "webhook.argo-events.argoproj.io" denied the request: template pubsub-workflow-trigger is invalid, unknown operation type create If I run it manually via kubectl apply -n argo-events -f sensor.yaml it says created. And after it the sensor is even visible by ArgoCD and marked as healthy.

Describe the bug

ArgoCD can't install argo-event's sensor, although the same sensor (taken from argo examples) can be installed using kubectl command.

To Reproduce

1. package example sensor and event source in helm chart
2. add argocd app manifest using this helm

Expected behavior sensor installed via argo cd

Update: Looks like it is not an argocd issue, but helm. When I try to install helm package via helm I get the same error:

helm install name name-0.2.108.tgz -f values.yaml 
Error: INSTALLATION FAILED: 1 error occurred:
        * admission webhook "webhook.argo-events.argoproj.io" denied the request: template nam-trigger is invalid, unknown operation type create

looks like the reason was in the incorrect yaml. I compared example with my code line by line and found it
