Using Junit assert on json array of elements fails on first element

I'm trying to use Katalon Studio for some webservice automation. I have been following this guide on how to parse returned Json body using jsonslurper. https://docs.katalon.com/katalon-studio/tutorials/parse_json_responses.html Everything is working fine as described in the guide. I wanted to see if I can use junit asserts, specifically the assertEquals() for better error text. Given we have this

import groovy.json.JsonSlurper

String jsonString = {"menu": {
"id": "file",
"tools": {
"actions": [
{"id": "new", "title": "New File"},
{"id": "open", "title": "Open File"},
{"id": "close", "title": "Close File"}
],
"errors": []
}}}
JsonSlurper slurper = new JsonSlurper()
Map parsedJson = slurper.parseText(jsonString)

def array1 = parsedJson.menu.tools.actions

String onlickValue1 = ""

for(def member : array1) {
assertEquals("Open File", member.title)
break
}

What I'm having trouble with, is that my assert will thrown an error when comparing the very first title element it encounters (which is "New File").

What I intend is to loop through all the elements in the array and assert my expected value against all of them. If my expected value doesn't exist, then I'd fail.

I feel like I'm missing something, because we've done something similar in the past with java, but I just can't see it here.

So I figured out the problem was my inexperience/ignorance. When looking for solutions online I failed to understand with absolute certainty what the code I'm trying to implement is doing. I was using a for.each loop to assert elements in the array against my expected value. Which of course was failing, correctly, for every element that didn't match my expected value. So I made it work by adding an if statement as below:

String expectedValue = ''
for(def member : array1) {
if (member.title=="Open File")
{
expectedValue = member.title
}
break
}
assertEquals("Open File", member.title)

Also a simpler way I discovered is to use assertJ in the following way assertThat(member).contains("Open File")

I understand there are better solutions to achieve what I'm trying to do. But for purposes of this question I considered it solved.
