Creating an Epic via API ignores multiple customfields

Issue Summary

I am able to reproduce this in alignsupport.  If you do a POST on the /align/api/2/Epics endpoint and pass it multiple values under customfield, it will ignore everything after the first customfield.  

No errors returned

Steps to Reproduce

1. Do a POST on the /align/api/2/Epics endpoint to create an epic.  Example JSON I used below.  Adjust IDs to your environment needs:

{
		"title": "Lorem Ipsum Title 2",
		"description": "Lorem Ipsum Description",
		"primaryProgramId": "584",
		"state": "1",
		"type": "1",
		"startInitiationDate": "7/1/2023",
		"targetCompletionDate": "12/31/2024",
		"customFields": [
			{
				"customfield_70001": [
					{
						"value": "ACC"
					}
				],
				"customfield_70002": [
					{
						
                        "value": "klein - 100 - 1.000 AT (FB/IT)"
					}
				]
			}
		]
	}

Expected Results

The epic will be created with data for both customfields that were indicated in the POST

Actual Results

If you do a GET for the epic that was created, you will see that only the first customfield was populated.  All subsequent data was ignored.  No errors were thrown during the running of the POST.
