And I installed my ArgoCD with ArgoCD Operator, and both ArgoCD and ApplicationSetController are the the latest version

What can I do fix the problem?

@jizusun : check invalid ApplicationSet has been created , kubectl get ApplicationSet -A and look for bgd-pr-testing @ishitasequeira : should we mark it as invalid

[jizusun]

Look at above example , your generators array is empty

Add this in your application set it will get fixed

generators:
  - pullRequest:

[rishabh625]

I'll recheck, u can too if zero array for geenrators is accepted , it think a bug should be reported
