Script Runner Merge Check: Code Snippets for approvers is not working

Question

I created a conditional merge check.  Then I copy in either the "Named user approves" or "At least one user from experienced developers group has approved" code snippet and my pull request can still be merged in despite the condition not being met.  I copy in the "Target branch is master" code and that blocks my code merge.  What do I need to change to make these work?

mergeRequest.pullRequest.reviewers.find {it.approved && it.user.name == "seniordev"}

and

import com.atlassian.sal.api.component.ComponentLocator
import com.atlassian.bitbucket.user.UserService

def userService = ComponentLocator.getComponent(UserService)
mergeRequest.pullRequest.reviewers.findAll { it.approved }.any {
userService.isUserInGroup(it.user, "experienced-developers")
}

The group didn't exist in the scope I was using.  To check that,  you use

import com.atlassian.sal.api.component.ComponentLocator
import com.atlassian.bitbucket.user.UserService
import com.atlassian.bitbucket.hook.repository.RepositoryHookResult

def userService = ComponentLocator.getComponent(UserService)
if (userService.existsGroup("experienced-developers")) {
   RepositoryHookResult.rejected("Merge rejected", "exists")
} else {
   RepositoryHookResult.rejected("Merge rejected", "does not exist")
}
