Should I worry about this error message?

I have a SwiftData Model which includes a property of type Array<String>.

@Model
 final class Handler {
    public var id: UUID
    public var name: String
    public var mailingAddress: [String]
    . . .

    public init() {
        self.id = UUID()
        self.name = ""
        self.mailingAddress = []
        . . .
    }

When I use this Model in code, the mailingAddress field appears to work just as I would expect, but when saving it (running in Simulator), I see the following logged message:

CoreData: fault: Could not materialize Objective-C class named "Array" from declared attribute value type "Array<String>" of attribute named mailingAddress

Should I be worried about this?
