swiftui - ShareLink with custom type produces error - Stack Overflow

I have a JSON file, which I want to share using the ShareLink framework. To do so, I created a Transferable extension for the class containing the data:

extension DataWrapper: Transferable {
    static var transferRepresentation: some TransferRepresentation {
        CodableRepresentation(contentType: .foodDataType)
        
        DataRepresentation(importedContentType: .foodDataType) { data in
            let wrappedData = try JSONDecoder().decode(DataWrapper.self, from: data)
            return wrappedData
        }
        
        DataRepresentation(exportedContentType: .foodDataType) { wrappedData in
            let data = try JSONEncoder().encode(wrappedData)
            return data
        }
        
        FileRepresentation(contentType: .foodDataType) { wrappedData in
            let docsURL = URL.temporaryDirectory.appendingPathComponent("\(UUID().uuidString)", conformingTo: .foodDataType)
            let data = try JSONEncoder().encode(wrappedData)
            try data.write(to: docsURL)
            return SentTransferredFile(docsURL)
        } importing: { received in
            let data = try Data(contentsOf: received.file)
            let wrappedData = try JSONDecoder().decode(DataWrapper.self, from: data)
            return wrappedData
        }
    }
}

Furthermore, I defined a JSON based UTType:

extension UTType {
    static var foodDataType: UTType = .init(exportedAs: "info.rueth.EasyFPU.DataWrapper", conformingTo: .json)
}

... and added it to the Document Types and the Export Type Identifiers sections in my plist file.

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" ".0.dtd">

Finally, I'm calling the ShareLink in a swipeAction of a View:

.swipeActions(edge: .leading, allowsFullSwipe: false) {
    // Sharing the food item
    ShareLink(item: DataWrapper(dataModelVersion: .version2, foodItemVMs: [foodItemVM], composedFoodItemVMs: []), preview: .init("Share"))
    .tint(.green)
    .accessibilityIdentifierLeaf("ShareButton")
}

When running on a physical device, the Share sheet opens and I can select, e.g., Save to Files. After selecting the folder and confirming, I get the following runtime error in the Xcode console and no file is saved:

Received port for identifier response: <(null)> with error:Error Domain=RBSServiceErrorDomain Code=1 "Client not entitled" UserInfo={RBSEntitlement=com.apple.runningboard.process-state, NSLocalizedFailureReason=Client not entitled, RBSPermanent=false}
elapsedCPUTimeForFrontBoard couldn't generate a task port
Failed to load item provider <NSItemProvider: 0x3033eb870> {types = (
    "info.rueth.EasyFPU.DataWrapper"
)}, falling back to original item provider
cancelled request - error: The process was aborted.

Especially the "Client not entitled" seems strange to me.

What am I missing?
