Additional mongo json properties show as null in graphql query, despite updated schema

Working with Data
1

A specific object/json/graphql combo in our setup has worked on production for more than a year. I have added some more properties to this object in Mongodb json collection and updated the schema, added data, which i can see in the collection, yet graphql queries only show the new property (which is an array) as null. I have tried the application graphql (nextjs), Postman and the mongodb website tools to query app services, but the new property is always null in the returned json. Am i missing something?

Here is the original query:

query {
	nav {
		_id
		key
		pageId
		children {
			alternateurl
			contentType
			key
			naame
			pageId
			pageLevel
			showonnav
			showonsitemap
			title
			url
			children .... etc
		}
	}
}

Here is the updated query:

query {
	nav {
		_id
		key
		pageId
		children {
			alternateurl
			contentType
			key
			naame
			pageId
			pageLevel
			showonnav
			showonsitemap
			title
			url
			infoItem {
				itemImageId
				itemLinkObjectId
				itemLinkText
				itemLinkType
				itemLinkUrl
				itemText
				itemTitle
			}
			children .... etc
		}
	}
}

the infoItem section, which is the new section, is only at one level, and does not appear at the lower nested children

Here you can see there there are values for the new properties in the collection. The schema has been updated to suit the new props (by the “generate” tool)

Here is a screengrab of the data returned from Postman - with the new property “infoItem” present, but with a null value.

Can anyone help with this?
